Hi Sorry you didn't get a reply yet.
Sounds like he'd like a little more sleep, I'd go with that unless you have evidence to show that it results in him being UT for the next nap or night sleep. Only way to really tell is if you try it for a few days really.
If you find you need to continue to cap the naps it's fine to have some A time between S and E to feed at 3.5hrs. So EASAEAS
hope that helps
