Hi Chili,
What would be of interest is whether you found more crud after waiting for a bit longer.
Am sure that you will catch some if there is a lot but not sure that 5 mins is enough for all the water/crud to get to the lowest point, especially if the stuff is well mixed and partially emulsified by having a powerful refuel.
For that reason refuelling at the end of the day is preferable although that would mean you will have to have a fair idea what you are doing next time you get the bird out.

PS Hope we're not going to debate for a few pages the OWT of condensation in non full fuel tanks!
