Roughly 11 (same as your original IIRC). The max & min range spreads out from there as tech increases.

I thought we'd come up with some racial crossover techs, but I can't seem to find that in the thread...
We still need three more, as below.

For temporal-grav, how about "Relativistic Stasis Generator", which slows down time for ships (when idle only) reducing maintenance. (Similar to crystalline thing, but ship-based)
