Default Does this sound right?

I was hoping I could get some help with this one. I am waiting on a replacement pH sensor but probably won't have it before I brew as they are on back order. I want to try my first IPA and I am using the recipe from Brewing Classic Styles.
2 row 4.4#
Munich .26#
Crystal 15 .34#
Crystal 40 .1#
I will be using 3.14 gallons of RO water. Thinking of using 6 grams total of Gypsum and 1.3 grams total of CaCl2.
Bru'n Water predicts a mash pH of 5.35
E-Z water predict a mash pH of 5.47
Brewer's Friend predicts a mash pH of 5.38.
Does this sound reasonable? I haven't used that much Gypsum before so a bit nervous about that. Thanks for your help.

You can always just add the gypsum to the boil vs mash.

Reasonable to me. Do not be afraid of gypsum, it really works in IPAs. I add enough to hit 300ppm sulfate in boil.

Interesting you compare water spreadsheets. May I ask which spreadsheet is most accurate to your metered results?

That will depend on the beers. It's sort of like having two rifles with the windage set too far to the left on one and too far to the right on the other. On a calm day neither will be accurate but on a windy day one will be more accurate than the other with which one depending on which way the wind is blowing and and the accuracy depending on how strong it is.

Thanks for the replies. My very limited experience so far goes with what AJ said. Nothing has been spot on (Brewer's friend came really close once but my meter was also screwing up so who knows) but I think they are getting me in the ballpark.

Never used brewers friend. In my experience, bru'n water was more accurate than EZ water. I started with EZ water and switched because of this. Of course, that was some time ago and I understand EZ water has been updated.

I have found (again in my very limited experience) that it has been a mixed bag every time. EZ water is usually the highest prediction followed by Bru'n Water and then Brewer's Friend. My meter seems to have crapped the bed pretty quickly so I don't know how accurate my reading were though.
