Well written on the warp speed dissertation. I enjoyed reading that, quite informative and you worked out the basics fairly well. All discrepancies aside with how SFB/SFC and the canon warp goes, we need a 'playable' warp factor. I think more thought needs to go into it, but will it be used tactically, strategically, or simply for disengagement? Once we figure that out we need to look at lag, sync and other issues that may affect speed... in addition to possible steering issues which become difficult the faster you go, so playability comes to bear again.
I think the upper limit on speed should be 1000. Imo, tho, thats too fast.
