That's what I got for yesterday and today, and more than twenty today received orphans, only one received normally!
http://prntscr.com/iwo5d0simple rule - never stake right after the fork, let the network clean itself.
especially if it wasn't smooth, multiple fixes, etc etc.
if somehow you want to test everything right away - make wallet.dat backups.

Yes I think its best to give it at least 12 to 24 hours before staking after an update to the new APR as I had a lot of "generated but not accepted" blocks even though I was on the right chain and was update to date. But now I am getting stakes and no more orphan blocks so the chain seems to be running smoothly like before the update.
