Why GACSTR+ is the default algorithm for tables?

[gadavidd]

I'm working with table propagators and then I realized that in IIntConstraintFactory class, the default configuration is GACSTR+ algorithm for feasible tuples.
At first, I thought it was due to the memory optimization used, once the specific options are STR2+ and CT+. But, I'm not sure about it.

The conditions were extracted from empirical evaluations, few years from now.
I suppose that this could be re-evaluated.
