RE: SAS available again

No worries! Just to reassure you for future interactions, I'm not given to attacking on the forum (unless provoked!) and least of all with people I respect. In fact, I was agreeing with you. The ill defined test conditions of the distortion level at 15kHz notwithstanding...my point was that quoting a specific lifetime is itself meaningless given the number of factors involved in determining wear. For a given tip, say a MicroLine in a PTGII tracking at 2g, you must get a higher wear rate than for the same tip in a V15VxMR tracking at 1g. Quoting 1000 hours as the life may give an indicative figure, but is clearly not going to be accurate.
The other point I was making about the wear rate was that if you play one record (not a test disc!), say, over and over, you will wear the tip at a greater rate than randomising the playback over a significantly larger sample of discs. Presumably this will be due to the wider variation in modulation level plus if you play back one single record, the particulate buildup in the grooves (shed from the tip) will accelerate the wear.
