Panela Yield Question

[LWTCS]

Hey guys,
For those of you that have been participating in the bulk buys from SugarDaddy,,,if you wouldn't mind sharing your yield results on a per pound basis please.
Further, do you find that the yield on a 20L (beer) kettle charge works out with the same yield ratio as a 50L kettle charge for example?

I have found that I could render right around 1.7 liters of keeper distillate @ 90% abv off of a 30L kettle charge with 10lbs of panela.
Does that sound consistent with what you guys are getting?
