Congrats on some great scoring and bowling!
But, no, don't rely on one factor out of many, many that determines how well you are scoring and how good a ball reaction you are getting.
As has been said so many, many times, surface+coverstock rules, 70% of a ball's reaction. Then there's the oil pattern, how well you're throwing the ball, how consistent is your release and ball speed, how accurate you are that day. Plus a thousand other factors.
The core's specs are only as starting point; once drilled, the dynamics of the drilled core will be very different from the statics.
Using balls whose core meets this apparent ideal will only limit your choices and possibilities.
