Did anyone manage to fix reported rate @ MPH for Zcoin with ccminer?

Tried:
-ccminer x64 2.2.3 cuda 9
-ccminer x86 djm34 2.2.x (.1 or .2) (which is the one suggested by MPH @ the Zcoin pool page)
-ccminer x86 "some other fix version" forgot which fork

With all the above getting around 50-60% ccminer rate

With ccminer x86 djm34 non cuda 9 I get worse ccminer performance (around 2800, down from 3050 with others) but way better reported rates (up to 2500)

Any ideas?
Should I just check how much I'm getting with one vs the other and just ignore what's being reported?

I'll also do some suprnova tests.
