Thanks for posting your EASY.
Im not very good at timing the feeds so dont know the distinction between E and A
Don't worry about it. A includes E anyway so we count A as anything which is not sleep. A begins as soon as he wakes and continues up to when he is asleep, including eating, nappy change, play, shush/pat - anything that is not sleep.
Your A times are not typically too short for age but it is important to remember A times are only a guidance. It does look to me like he would likely nap better with either slightly more A time or slightly more stimulation. As you say, today you did more with him, he slept better as he will have been more stimulated and therefore more tired. You might want to increase the A time by 10 mins too. It looks like by the third nap yesterday (and quite longish A times) he was eventually tired enough to sleep a better length. The aim would be to return to all naps being of decent length of course.
Keep looking for cues but also be aware some LOs do like longer A times than others. Mine liked a very long first A and shorter for the rest, other babies like a shorter first A and longer for the rest, this is why we look at the individual sleep needs and so on.
