Hi, sorry for the delay in replying, but unimportant annoying little things like sleep and work just got in the way... I checked the lights. The settings appear identical, and final rendered images are the same as far as I can tell. As Opera has said, purpose of test is to compare identical settings, however, just in case P6 had some particular problem with the small bucket size, I reran the test with a bucket size of 128 P5 - 93 sec P6 - 152 sec
