Yes, using paper test-strips, I've been verifying a perfect color-match with unused XTOL. I'm using XTOL as an 8.2 buffer.

My last test boosted the PG from 3% to 7% with a noticeable drop in density. I wish I had a better understanding of the chemistry behind all this.
No, I tested the developer immediately after mixing, so neither concentrate nor working solution had a chance to settle. The working solution has now been sitting for hours, and a check a minute ago shows no separation.
