Are you testing your salinity with a hydrometer or refractometer?

This is my preferred method... but I've been wondering:
Has anybody done the math to figure out what percentage of SW topoff would have to go in to raise the SG a certain amount, e.g. on a 100g system, if one wanted to go from 1.024 to 1.026?

I only ask because if an approximate amount of evap replaced with SW could be figured, one could estimate how long the change would take, and maybe adjust the SG of the topoff water to speed up or slow down the change in the system.

It will certainly help the wallet.

I'm sure it could be done, but I don't think it's all that important. Even the fastest evaporation rates are still slow enough to safely raise salinity. Drip acclimation is rushing compared to the rate of evaporation.
