Sorry, what does "increase the effective size of the stringbed" mean?

Could you include this link in your OP?
I've noticed some people on here think MgR/I=21 is optimal, instead of fine tuning their racket. I assume these people have just read the OP, not the entire thread.

What about if you wear it midarm/forearm? Would it affect Mgr/I?I moved my wristband up to midarm and noticed a difference in swingspeed.

I think weightlifting increases hand and wrist muscle mass. Should mgr/i be re-tuned if you lift weights?
