Lots of diverse responses. I am still pretty fuzzy on the theory end.
Ring flutter? Does this really happen? How does the wider 2nd ring
gap prevent it? What is the downside of trapping pressure between
the rings if this really happen; I cannot see there being much pressure
trapped there if the top ring is working.
I checked some new in the box rings from two different manufacturers
and there was no mention of special gap for ring 2.

Total Seal now specifies this as well. It was explained to me that it was to
prevent trapping pressure between top and second ring.
Agree, go with manufacturers recommendations.

Wiseco says: The gap on the second ring should always be larger than the
top ring end gap, this will help to reduce top ring
flutter or lifting.
That's right off they're installation "pink" sheet. Maybe some piston
manufacture think different. I would go my what
your piston manufacture says.
