ASG-29 water dump rates

Replies seem to be focused on dumping from full (or ballast volume at departure if MTOW limited) to empty, such as on final glide. Does that not miss the intent of the activity?

Measuring my dump rates is on my to do list too. On a day that's not as strong as predicted, I want to know the rates so that after an intermediate dump in flight my LX has an accurate weight/loading to use in its calculations. This will be from full, or ballast @ MTOW if limiting, to 50% or so. Thus its this 'range' I'll be measuring, with the wings and fuse in an 80kt flight attitude. The slowing of the dump at lower volumes is inconsequential as on final glide, my only concern is dumping it all before landing.

Please do share your data.

Jon, if CJ's numbers match yours it'll be coincidental.
His glider is antipodal.

Our ASG29Es dumps about 65 liters a minute starting from full.
From 50 liters remaining it goes down to 60 l/m.
From 30 liters remaining it goes down to 50 l/m.
Last 10 liters go slow at about 35 l/m.

Tail is 1 liter per 8 sec.

Adjusting the system can make quite some difference.
