Attack Speed is supposed to be equalized, too. Or rather, reduced by the same multiplier as Combat Speed for Speed Equalization purposes.
IDK if any Calc for Jotaro's speed, so I'll assume it's
Speed: Superhuman (Ran approximately 400 meters in 22 seconds
[21]) & baseline MFTL.
The Superhuman is roughly 18.1818182 meters per second.
Baseline MFTL is 29,980,000,000 m/s. About
So assuming the Superhuman is reduced to Baseline Average Human (5 meters per second.), that's being divided by about 3.63636364.
So.... 29,980,000,000 m/s / 3.63636364 = 8,244,499,991.7555000082444999917555 meters per second
In other words, even in unfavorable Speed Equalization conditions, Star Platinum is still operating at over 8 BILLION meters per second? Seems kinda unfair, whether against Robbie Rotten or not, since SP is basically still unfairly fast for a lot of opponents.
So if Star Platinum is NOT supposed to be Equalized the same way as Jotaro is.... I'd call this a speed-blitz since SP still ends up solidly into FTL+ against an opponent who at best, brought a Relativistic to the fight.
Nothing stops Star Platinum from overwhelming Roboticus & Robbie alike other than 2 meters range.
Star Platinum is Speed Blitzing DESPITE Speed Equalization applying to its user & not being a summon & present at the very beginning of the match. Whether against Robbie or not, that feels a little wonky to me.
