I`m puzzled.Am not really familiar how things work here. Why can`t I edit and is there an edit function?

off-spec b.p. I'm wondering how common it is for head rackets to be off spec, and what is the range of variance from their stated balance point. I have a Metallix 4000 with a b.p. of 295mm even with a Karakal Super PU on! And the stated b.p. is supposed to be 284mm. It does feel good though; maybe Zhou Mi used a similar head-heavy 4000 for those powerful smashes.
Sounds really interesting and technical.How do you measure B.P and how is the B.P affecting performance of the racket?
It's not that technical; i only employ a crude test - ie. balance the shaft of the racket on my little finger, and measure the point of balance from the bottom up. I must mention though, that the original grip has been replaced by the Karakal PU, and not overgripped with it.
Strung or unstrung (Should measure unstrung, makes about 10mm difference but best if measured yourself and depends on how far you regripped it)
Strung. It's only a crude test that i employ, relative to the other rackets i have with similar setups.
