I don't know about the rest of you but for me Reaper's peak reading is always .1db low.
The reason I say this, any time I normalize to a certain level, it will end up reading .1db low. Or record a sign wave test tone at a certain level, it will show .1db low.
When I set my master limiter up for a max of -.5db, it comes out at -.6db.
It's no big deal, I've gotten used to it, I don't really care that my mixes are .1db lower, it's better than if it went the other way, .1db higher.
