I noticed the same thing that the 95oct map works well running 93 oct with around E30. To have absolutely no corrections on the E40 map you'd need over E40 in reality (probably closer to E50 as you say).
In terms of performance there's not so much in it I think between 95<->e40 except top end where the E40 is marginally faster. WGDC only goes over 90% shortly when you hit 6000+ rpm so I wouldn't worry too much about it personally. All 3 ots stage2+ maps by MHD (also the 93oct one) run really great combined with a bit of ethanol to perfect the timing advance. The MHD ots tunes seem really catered towards high octane.. with ethanol being the easiest solution for that.

The only question I had was the rail pressure act vs target, mine does dip for a tad between shifts, is that normal on the e40 map? I also changed my RPM limits for each gear so I was able to get better draggy times while also preventing the WGDC from pushing into the higher 95+ like I've had before. Here is a log on e40 with e46ish, could you let me know if this rail pressure drop is normal as it is only during the shift for a quick second?
