I think a reasonable rule of thumb is that where a country qualifies a synchronised team one of the pair is also likely to be competing in the individual events. GB has secured the maximum number of quotas available and although they brought 15 divers to this event to cover the 16 places I expect that they will likely select a team of 12/13 divers with some competing in both the individual and synchronised events.

FINA will be forced to break their rules by the courts because of a poorly written qualification document.
 
Unless athletes and NOCs decide not to fight it...

The qualification rules clearly state: ˝The 18 highest placed athletes at the FINA Diving World Cup 2020 will each obtain one (1) quota place for their NOC with a maximum of two (2) athletes per NOC˝ 
 
So this means all semifinals here have a spot at the Olympics. This doesn't mean 18 athletes from this competition will qualify, because also NOCs who already have quotas from before, are also included in this TOP 18. I understand your math, but you must know that FINA was wirtting these rules under the assumption that only 136 will be allocated during the process. It is now clear that this number will be overreached, and there's nothing FINA can do about it. They can't change the rules retro actively. 
 
But there might be a loop hole in the rules: ˝If an athlete who has obtained a quota place in accordance with FINA Rule BL 8.3.8.3.3.4 has not been entered to the Olympic Games, the quota place shall be reallocated˝ Does this mean the athlete with a quota has to compete in one event at the Olympics or else the NOC loses the quota? This might be a way for FINA to get closer to 136 limit....

the 18 semifinalists guaranteed their ticket for Tokyo (respecting the NOC limit etc.), so they're safe. But those reallocated quotas on Wikipedia are a guess, because no one knows how many athletes we will have competing in two events and so.... But TOP 18 is qualified officially

UCI has finally updated their qualification documents.
 
Basically, the Olympic rankings for cross-country, BMX racing and BMX freestyle will include the next two World Cup events. If they don't occur, they will take the Olympic rankings on the June 7th update.
 
Also the BMX racing World Championships quotas have been reallocated to the Olympic rankings

Probably they will pick who has the standard.

Skateboarding - Dew Tour will be in Des Moine, Iowa, USA
 
Gymnastic(Artistic, Rhythmic and Trampoline) - 2020 Oceania Continental Championships from 13 to 21 May in Gold Coast, Australia.

yes, FIE rankings are OK, it's the qualification recap that's wrong (and it can't change, as there are no more events to be played until the next Olympic Games, except for the last Foil Individual GP)...

CAF–CONMEBOL play-off 10 - 13 april (turkey)

The Executive Board of World Triathlon has today approved the restart of the Olympic and Paralympic Qualification rankings from 1 May, 2021. The Asian Championships will also be counted as an exception as it takes place prior to the date of the restart. Concurrently, the IOC and IPC have been asked for the relevant qualification criteria to be updated. The Olympic Qualification Period will remain open until no later than 21 June, while for the Paralympics the Qualification Period will be open until 15 July.

The restart of the Olympic qualification period will mean that athletes will have the opportunities to compete in a total of 6 events, including World Triathlon Championship Series Yokohama and Leeds and World Triathlon Cups in Osaka, Lisbon, Arzachena and Huatulco, with racing planned in three continents during the window. The remaining Continental Championships and the Mixed Relay Olympic Qualification events are also planned to be held during the qualification period. The world rankings will also reopen on 1 May.

World Rowing has updated the qualification system:
 
"Where there are no further crews to which qualifying places can be allocated, such places shall be added to the qualifying places in the same event at the Final Qualification regatta."

If the Oceania qualifier isn't rescheduled the quotas will go to the highest ranked eligible nations in the May World Rankings. Currently leads for men's singles, for women's singles and for mixed doubles.
 
Of course it is quite likely New Zealand will decline their quota so it will then go to Vanuatu.

We have three qualification events for skateboard : 
 
Dew Tour, TBA, 17-23 may Street world championships, Rome (ITA), 31 may-6 june Park world championships, TBA, 14-20 june

The WBSC Baseball Americas Qualifier is expected to be held in early June (exact dates/venues to be confirmed) in Florida , with the WBSC Baseball Final Qualifier to follow from 16-20 June in Taichung .

So the British have released a second set of qualification standards.
If an athlete fails to reach the Olympic standard then these must be achieved before GBR will allow them to enter via the World Athletics rankings system

Even though these meetings won't be listed here on the first page, you might be interested.
 
April is supposed to be the decisive months for German swimmers. There are four meetings in April, which are FINA approved qualification meetings. And after these four meetings, the German swimming team will be completed. Or at least this is the plan.
 
The four meetings are:
 
Würzburg, April 3rd - 4th
Magdeburg, April 9th - 11th
Berlin, April 16 - 18th
Dortmund, April 17th - 18th

Yes, the last remaining quota in Men's single sculls goes to  
 
The one question from this regatta remains who got the reallocated quota of LW2x. My guess is Latvia, but could as well be Canada. We'll have to wait for World Rowing to make it official.

To complete, the world cup event became a test event only. As a precaution the event will take place with only japanese gyms to test the venue. Without the qualification to obtain there is no need for athletes all around the globes to travel to Japan by this trouble time.

The rowing regatta is confirmed, and my guess is so will be the events in diving and artistic swimming, since these will all be direct qualification events and athletes will be given exeptions to enter Japan.
As I understand, the gymnastics World Cup was cancelled because it wasn't a qualification event anymore so there is no need to host it

You might be right, I guess we'll have to wait to see what World Rowing says

The Pan-American championships were scheduled to be held between April 8-11. The ICF will
activate its contingency plan to allocate the quotas based on previous event results, in consultation
and with the final approval of the International Olympic Committee executive committee. 
 
This means either using the World Championships or a bust.

And I was thinking that Sailing had finally defined all events. 

The sailing event, La semaine olympique de Hyères, which should give european quota for Laser and Laser Radial is canceled (source in french : https://www.lequipe.fr/Voile/Actualites/La-semaine-olympique-de-hyeres-est-annulee-a-cause-de-la-pandemie-de-coronavirus/1228666).
