We had the standard decompression stop at 10-15 feet and I used
a dive computer. Part of my issue was with my jaw clamping on
the regulator too hard, and I developed a bad headache, but I
also felt perhaps it was a bit much. Not every dive was that deep.
But I do believe the effects are cumulative. I just reached the point
were I felt it better to back off.

The last 30 feet is 100% change in pressure, so I question
on deeper dives whether there should be more than just
the 10-15 foot stop.

Could very well have been. I was relying on the dive computer
both on rate of ascent and decompression stop.
