The sequence simply changes from:
1) Apply resin; 2) Expose through mask; 3) "Wipe" or vaccuum off uncured
resin; 4) Expose high-intensity UV; 5) Apply wax; 6) Chill wax to solidify;
7) Mill layer to thickness

7) Expose high-intensity UV
Therefore, the very thin film of resin that cannot be vaccuumed off is not
ever cured, so no "skin" is produced between layers, reducing dewaxing
effort and even eliminating the requirement for citric acid to be used (now
just warm water works).
I have not heard of the "Extended Solid Ground Curing" term, so cannot
enlighten you about that.
