3 to 2 naps?

Did anyone transition from 3 to 2 naps without a micro nap first? Can I please see your wake windows before and after transition?

My 6.5 month old is sleep trained. He has been fighting both the second and third nap and we’re on 2/2.5/2.5/2.5. I’ve always had to cap this first nap to 1.5-1.75 hours but there has been two occasions where he woke up on his own (1 hour and 1.25 hours). He goes down for bedtime within 10-15 minutes. Wondering if it’s time to transition.
