Is a TRUE aerobic threshold/ lactate threshold pace 88, 90, or 93%

you're over thinking this

Lactate threshold is different for every single athlete/person. The more aerobically trained someone is, the higher their lactate threshold will be. But then, one athlete may start at 88% and train up to 93%, while a team mate might start at 80% and train up to 85%.

So there are no magic numbers or paces or percentages of paces which fit every athlete.

Yes.

What the heck is maximum effort?

Ask Ben.
