As with the women, here is the scenario for men: there are 59 divers qualified for individual events, leaving 9 spots to reach the target 68 competitors.
From those 9, 3 will go to divers from , & , as neither of them has a second quota in the corresponding individual events in which they earned places in synchro. However, the other likely half of those duos (Marsaglia, Terauchi & Sereda) qualified in individuals so their quotas in synchro won't be counted.
So, we have 26 synchro only divers that will compete for 6 quotas.
Woo Ha-ram qualified in 3 events, and is likely to be selected in all of them, so he will vacate 2 of them, and probably so his synchro partner, so we're down to 23
Daley & either Goodfellow or Laugher will surely double, so now we have 21
For , I project Kuznetsov & Shleikher to compete in both springboard events. We take 2 off, and reach 19
The last country I'm sure will use a double starter, it's Canada in 10m (either Szombor-Murray or Riendau).
And then there were 18/6, so no chance for reallocation in both men and women isn't likely to happen, as the target quota will be surely be surpassed in men and if those few that might remain from the women quota, are likely to be used for the male competitors.
