Yes, definitely. Slowly, you will reach continuous pushups in 20th set, and then 21st set, and then 22nd set....

Is your 'day 3' the second day of the regimen? I am not sure what you mean by 'measuring rest time'. What is expected is, you hit the start timer button, do the first round of pullups, pushups, and squats, and hit the stop timer button. You may have taken brief pauses in the first round to catch your breath but the timer keeps running. You stop the timer only after the first round is completed. Then, you take at most 3 minutes rest and then start the second round and time that round.

My opinion is that it is okay to do the max reps in the first round. I think 25 is the appropriate number. I reached 25 reps in the first set on the judgement day. I take 5 to 10 seconds and do 10 more. I take 5 seconds rest and do 4 more. And then 2 more. That is how I complete my 41 in L4. When I reach higher rounds, I am planning to keep the first set at 25 and build up the second set to 20 and third set to 15 and so on. I would not drop back to L4 if I were your position. I would continue to focus on building up sets. It may take 3 months or 6 months, just keep at it and muscles tend to build up very slowly.
