What I think is happening is that the skins are overly tough due to the very low absorption being used. How much do you mix the dough? I have found that if the dough is mixed in much the same manner as a regular pizza dough shrinkage can be a problem. You might try this: Put water, salt , oil and yeast in the mixing bowl, immediately add the flour and begin mixing at low speed, the total mixing time should only be about 1.5 to 2-minutes. You DO NOT want to see a dough, instead you want to see a mix of flour and wet particles, much like you see when making a pie dough. After mixing, transfer the entire mass to a suitably sized container, cover and allow to ferment at room temperature as you are presently doing, then turn the dough out onto a floured work surface and cut into desired weight pieces, lightly form into “pucks” like hockey pucks, place on a lightly floured sheet pan, you can go two high if you place a sheet of parchment paper between the layers, slide into a plastic bag and allow to ferment at room temperature until the dough pucks can be sheeted into pizza skins, of place into the cooler for use on the following day. If this doesn’t work, your only other alternative is to use some PZ-44 or Dead Yeast/Red Star RS-190 as a reducing agent in the dough to relax the dough memory characteristics.
