I think we wrote the same thing. 🙂

Me: "The literature reports a few cases of prostate cancer progressing while PSA is still low-ish (e.g. < 2.0), but personally I haven't yet read of progression when PSA is < 0.01 on the ultrasensitive test."

You: "Actually @northoftheborder The literature reports a few cases of prostate cancer progressing while PSA is still low-ish (e.g. < 2.0), "

Have you read of any cases of progression with PSA < 0.01? I haven't yet, but I'm keeping my eyes open.

The article you linked is interested: it mentions that the -lutamides can suppress PSA even in cases when cancer might be progressing, but it mentions only "quite low" and "nadir" vaguely, not fully undetectable PSA specifically. It would be interesting to know if any of those cases involved undetectable on the uPSA test.
