I was never one to worry about how fast or slow I'm rolling the ball as long as I keep hitting my mark but something struck me as odd today.

A new Qubica scoring system was installed at the lanes on base and noticed that it registered my MPH from 13 to 15.

The old system (not even sure what brand) registered at 17 to 18 MPH.

The mechanic stated the old system actually registered in KPH.  If that's the case, 18 kph would equal 11 mph.  I know I roll the ball faster than that.

Like I said, doesn't really matter in my overall game but....

I use whatever ball works for me.
