Default Mini Mash - sparge question and boil amount

I've been playing with numbers and found something that raised a big old "?" above my head.

Main question - in a mini mash is there a problem with "sparging" or rinsing in this case with MORE water??

I ask this because . . . ..

I normally have been working with LME. Adding LME to a boil is adding liquid and I was making sure the PH of my water was correct (using Gravity points and amount of LME and so forth).

However - switching to DME I'm no longer adding liquid to the wort and thus my total wort being boiled will be slightly smaller.

SO - to make this up I thought I would just sparge (rinse) with more hot water.

Comments??

Yes. Oversparging alters the mash PH and can lead to extraction of tannins, leading to astringency.

Should have add this is a partial boil also!

So would you suggest to get my boil up to 2.5 gallons just add water?

If I start with 2.5 gallons
The mash grains will reduce the volume to 1.7 gallons
Sparging will make it 2.2 gallons and I want 2.5

Just add .3 gallons of water to the wort?

Or am I being water obsessive LOL
