Yep, I think I've seen this one or similar before. And, yep, it works for me.
I also recall learning that you should always tune DOWN to pitch with a floating trem - I find this really difficult to do, I've always tuned UP to pitch, stretch and tune up again... if I go past I tune down again and try again. I have found if you can "tune down to pitch" it does seem to stay more stable on a floating trem. But, in my case, I found it such a pain to tune like that, that it wasn't worth the effort to me.
But what this guy was describing really does seem to work (as long as you've removed or alleviated as many of the "sticking points" as possible, ie sort the nut, lubricate the string tree(s) etc, etc)
