Question Stephen aka Porsche PHD - Your take on the boost/CR balance?

Generally speaking & for the benefit of everyone:

For a fully optimized and tuned CIS system (Adj WUR, IA fuel head, twin plug, K27 HF turbo, 965 IC, Tail WG, AFRs virtually level from top to bottom/12:1. Runs about 10 track days per year.

What would you prefer to see - lower CRs and 'higher boost', or vice-versa? Could you elaborate?

My own data point: I am currently at 7.5:1 with .9 bar boost.

Intended as an open discussion with Stephen's input as to actual experience. Thanks in advance!
