I'm on record for well over a decade as disagreeing with this
prescription. Changing the swingweight using length, clubhead weight,
or shaft weight changes the performance of the club roughly the same.
Changing the swingweight using backweighting (which is really the
same as futzing with the grip weight) is very different -- and much
less predictable as to its effects.
Both theory and empiricism say this.
For the theory, see http://www.tutelman.com/golf/design/swingwt3.php#graphs
For some recent test results, see
http://www.hirekogolf.com//hireko/webpages/tech_articles/system_q2_experiment/system_q2_experiment.html
On a completely pragmatic basis, anybody trying to match swingweight
closer than one point is wasting his time. That little difference has
no practical effect, neither in performance nor feel.
Hope this helps,
