RODI numbers

I just replaced my membrane for the first time I purchased the Spectrapure 99% rejection rate. Numbers seem right to me but not sure if I need to trim the flow restrictor or not.

60 psi of water pressure
TDS 300 from Tap
TDS 2 from RO
TDS 0 from DI
TDS 315 from waste

60 seconds 145ml of RODI water
60 seconds 650ml of waste water

Waste TDS seems low to me
