Kosmik Governor response

Hi,
I'm wondering it this governor response is normal.
Setup :
LOGOXXTREME 700 + KOSMIK 160 HV soft 4.8
VBAR NEO + VBAR CTL
Kosmik mode 4 wit Ri 14mOhm and Pgain=6
Motor : kontronik 800-48L with 18T pinion
Battery : GA5000 60C with about 20 cycles
RPM sensor : Hyperion rpm sensor into NEO rpm port

In the graph you see the first part of the flight (PWM=79 1950rpm) : nothing too bad doing pirofunnel/backward rolling circle/funnel-waltz

second part : (PWM=83 2030 rpm) here I am worried,flying 4 square rainbow with rool and flips, Is my rpm really dropping that low ???

last part : ( PWM = 83 2030 rpm ) just giant rainbows with half rolls...upwind and downwind

Anybody with Kontronik kosmik/pyro motor to compare ?

Regards,
Kurt

Issue resolved. Went to 19T which gives more headroom to the governor and RPM deviation is much less now...
