Is it possible for a 75 gpd RODI to produce more than 75 gpd?

Maybe I am imagining things but it appears that my 75 gpd RODI is making more than 75 gpd of product water. Fewls/looks more like 100. Is this possible?

7 Stage RODI
TDS into Cation stage is 1
TDS into Anion stage is 0
TDS out is 0

70 psi water pressure into membrane

The gpd rating is based on a specific pressure temperature. The difference between 75 & 100 is close enough it is probably reasonable

With higher pressure and warmer temp it's possible. I have a large RO system, which is rated at 1,000gpd, but uses two 600gpd membranes. The rating is from an average pressure. At 80psi it will produce a gallon per minute, well over its rating.

Thank you.
