I have always looked at ballasting as a % of of the unballasted weight.

At 15% I can tell the difference.

For a Radian at 28 oz that is about 4 oz
For a 60 ounce Supra that is about 9 oz

I have rarely every felt the need to ballast more than 25%

Again for the Radian that would be 7 oz
for that 60 oz Supra that would be 15 oz

If I have to ballast more than 25% I better be flying for a world championship because those conditions must be wicked!

I ballasted my Supra at 60% once, just for testing. She flew just fine into a 25 mph wind. Clearly the sink rate was higher but I was able to push right through the wind to find lift that I probably would not have reached at 25%. But the sink rate was certainly much higher. And it landed fast.

Naturally your smileage will vary.
