My exposure time is less than 1/2 that with about the same conditions.

By tests, my paper is 5 stops slower than enlarging paper on-easel.

As for the uneven coatings, did you use any Photo Flo? Lack of a surfactant can cause some sever problems in coating. Denise uses Photo Flo 600 and I use Photo Flo 200. They differ by a factor of 3 in concentration and one uses EG, while the other uses PG for lower toxicity (PF 200). I use PF 200 due to the lower toxicity and also the fact that I can use 3x the amount and this leads to better accuracy in repeat experiments. It is hard to measure a half drop.
