Erratic OHR readings after update to 15.10

Does anyone have erratic OHR sensor readings during activities after update to 15.10?

Noticed that after update to 15.10 during my low intense runs when I barely sweat and perceived exertion is definitely easy OHR shows 115-120% of max HR trashing my Vo2Max and other metrics in runalyze. I never got such crazy readings even during running interval workouts.

Did a run today again, but recorded the session using adidas running+chest garmin hrm and using the instinct ohrm. For comparison imported the run recorded by instinct into adidas running app.

First screenshot is chest garmin hrm

Second one is recorded by instinct

Is there any way to downgrade Sensor hub? For me OHR sensor became just useless, measurements are accurate only when I'm resting.
