Yesterdays brew, the pre-boil PH was 5.4 and post boil to fermenter was 5.28.

My prior brew days with these 2 recipes have had a constant 72% to 74% efficiency and I always fly sparge. Brewing with the water builds has raised me to 84% and 86%. I will probably have to tailor my grain bills now.

I don't do them so I don't recommend them but that doesn't mean that I am recommending that you don't do them. If they improve your beer then you should certainly do them and many brewers do. Adding additional calcium salts can lower kettle pH, for example, as, obviously, does adding acid to the kettle. If you wanted lots of sulfate for some reason but were afraid that the extra calcium might drag mash pH too low you could withhold some of the gypsum for the boil.

As I have no experience I can't give any advice more specific than that.

Every IPA gets a post boil gypsum addition to arrive at a total 300ppm sulfate. Been doing it since I read Foster's Pale Ale in the 90's. Seriously, it is a must for IPAs. Dial in your mash and sparge pH, then "add salts to taste" to boil.

Nuggethead, I get similar efficiencies and yep, just scale the recipes back.
