I still don't like the idea of dumping anything that can end up on the
course. it is cumulative over the day and you know we can have hot days and
we can have cool and damp ones as well. if it an 90 degree dry day I can see
the effects being small but what about a 60 degree day that is overcast?? if
you allow something like that I don't think you can put an evaporation rate
clause in. It might be fine for a personal meet but at speed week the course
can get torn up enough with out adding water to it as well. With your P51 it
does not seem like it could really effect the course for other planes on the
ground might be another matter. Personally I think water content in and on
the course has bearing on the traction available and that is the final
governor for speed.
