Replying to Running a higher din setting on your heel

So I I've always had my Marker Squires set at 7 which is what the guys at the shop told me. Recently though as I've been progressing, I've started doing nose butter's and nose presses and so on I started popping out, I talked to the guys at the shop again, and they said maybe try turning the din on the heel up so I did, but it wasn't enough, after I a couple tests I turned it all the way up to 10 and I quit popping out. Now I'm concerned after reading some threads that this was a bad idea.
