Yes, it appears to be staking at around 10%. This could be a fluke due to skipping stake for periods of time though. Keep in mind that the private keys were not all 100%/year, there were others as well. Not sure if the 10/20% keys are still functional after the code change on 4/20?
As of 4/20 all keys are 100%
New keys were not issued the rates for all previous keys was changed.
