It's not about whether he is "competent" or not. I'm sure he has his routine down pat and can do it in his sleep. The issue is what sort of repeatability he can achieve and what accuracy he can achieve. I don't doubt he can achieve reasonable precision given that we know he uses a USB microscope to measure SRA. I would also be curious whether he has validated and verified the arm positioning and dimensional accuracy himself and whether has used an independent tool to set the alignment on the Technics or whether he is relying on the L-gauge. If he has used the L-gauge then his alignment accuracy is heavily dependent on the accuracy with which both the arm was centred in the plinth and whether he has verified the tonearm dimensions. You may not have done the process study, but I can tell you having disassembled and measured up several of my Technics arms for rewiring purposes that there are variances in the total length and offset angle, which, if not taken into account, make the L-gauge a rather inaccurate tool. There is a big difference between accuracy and precision.
As for his test, it is not clear if he is trying to compare the "package" which includes the manufacturer recommended alignment or whether he is trying to compare the actual "decks" themselves in terms of pitch stability, vibration isolation etc etc. If the latter, then he should have chosen the identical alignment for both decks.
