No argument from me there! You gave me the impression much larger values would go un-noticed.
To ruminate on a 0.01 difference would be ludicrous.
BTW Ceravolo just e-mailed me he never Star tests (!) ....does a whole bunch of other stuff... but commercial constraints require him to produce certified optics even when its raining or the seeing is crappy!
Agreed there are many producers of excellent optics out there, with well deserved reputations....and, Strehl ratios aside, perhaps that is how a novice might best find his or her dream telescope.
Have a good one!

....I buy an optic made by Christen, Zambuto, Steve Kennedy or Peter Ceravolo, I don't need to look at the strehl number to know that it's as good as hands can make it and I am happy to buy it.
