Difference between 2nd and 3rd Foundation

I have been doing 4 Foundation noting daily for several years. Periodically I go through the exercise of 15 minutes separately noting each Foundation. No questions about this process up to a week ago. Since then I question whether some phenomena that comes up is 2nd or 3rd Foundation. Is this pleasant feeling vedana or 4th Foundation? Is this unpleasant feeling vedana or aversion? Anger, restlessness, attached, etc., are still easy to categorize.

Also, I was told long time ago that only 10-20% of vedana was neutral with the rest being either pleasant or unpleasant. This scripted my noting responses so I would seldom note neutral. Lately I note maybe 40-50% of vedana as neutral because I can't decide whether it is pleasant or unpleasant.

None of this really impacts my noting but is very interesting to me. I don't think about noting while meditating but just come up with a word. Noting for me is to point to a sensation anyway. But, I think the experiential question of what is vedana is very important.

Any thoughts?

Somewhere in the Buddhism Before the Theravada series, John Peacock said that neutral vedana is extremely hard to notice. I think his reasoning was that if you noticed something at all, then the vedana was probably not neutral to begin with, but had a subtle pleasant or unpleasant tone to it.

Let me know if you find it in there

Personally, when I note vedana, it's pretty hard for me to notice which sensation the vedana actually comes from. Because the chain of dependent origination that fires from the sensation is very fast, it could be the sensation, the reaction to the sensation, the reaction to the reaction to the sensation, etc... My noting speed is simply not fast enough to accurately catch it all, and the original sensation is gone by that point.

So, I simply note if what I'm feeling is pleasant, unpleasant, or neutral, and don't focus so much on the what the originating sensation was. Sometimes there are runs of pleasant, sometimes unpleasant, etc. Sometimes it's all foggy and neutral.

I'm curious if others have this same experience.

Vedana is always associated with a 1st or 4th Foundation phenomena for me.

My experience is different from your Peocock reference.
