I have used this method as well as the record mentioned to set VTA with good results. http://www.tnt-audio.com/sorgenti/vta_method_e.html
I am more of a set it and forget it kind of guy. Mostly because I can't hear such small changes from my turntable which is not in the sweet-spot but off to the side quite a way from the listening position. One of my TTs has a Terminator tonearm which allows easy VTA adjustments on the fly but I do not wish to stand there and try and dial it in for each record. I'm not saying it isn't worth it for some, but I'd rather be listening!
That said, I have used a USB microscope to confirm my settings by ear and they seem to be very close (within 1 degree) to the supposed magical 92 degrees. OTOH, who decided that the playback SRA needs to be the same as the cutter angle? The cutter angle is a compromise between all sorts of parameters including getting the tool to cut in such a way that the waste material curls off properly. Those with machine shop experience will recognize that. Some of those factors have nothing to do with playback! Just an opinion. No facts involved!
