Do you ever hit the conga heads in the middle?

Hi guys,
First post here. I am a public school band director finishing up my 2nd year, my major instruments are trombone, piano and organ.
I recently purchased a set of LP Aspire Conga's for my band and LP Aspire Bongo's. The man at the store where I purchased is a professional hand percussionist who plays throughout the greater Cleveland/Pittsburgh area. At any rate he showed me a few techniques on the conga's. All the techniques he showed me, however, were played on the edge of the conga's. My colleague in the choir department here would like to borrow my conga's and he has a student who claims to know something about how to play them. This student whats to make them sound "deeper" by smacking them with the bottom of her hand in the MIDDLE of the head. I was not shown this technique, and I wonder if the student knows what she is talking about. I don't want to break the head.
Thank you.
