Phil, Rog posted the link to JVS's Centa conversion thread.
I was on it, but he beat me to it.
I'm very familiar with the old Harley type compensator, but not with the Centa. I'm not sure, but the way the pockets are shaped in the Centa, it may allow more wind up from loaded to un-loaded torque. If the wind up is more that 10 to 15 degrees, it "may" cause that sensation of slipping.
I think that it's anyone's guess at this point. Not everyone is experiencing the "slipping" sensation either.
