that of/ that at/ those of

Good greetings, again!

While reading something online, I happened to come across this phrase and find it faulty. A learning curve is a rate someone learns something "at". How could it be "of" there then? It was a well-written article (in BrE, I suppose), a tad explicit, though.

"speed up the learning process far beyond that of traditional learning curves"

Thanks. So, is it correct to say "speed OF curves", while "curves" meaning "rates"? I, by the way, thought it referred to "learning process".

What if "speed up" is replaced with "accelerate" or "expedite" in the original phrase, would it still be as fine or would "that" need to be changed to "speed" for the phrase to be correct?

Thank you, again.

Thank you, CJ. What if It were only "speed up the learning process beyond traditional learning curves", like speeding up a process beyond a rate? Still faulty?

It sounds all right to me. The faulty part was the phrase "that of", and this version does not contain "that of".

Thank you so much, CJ. Would it still be fine if one says "accelerate" instead of "speed up"? I just want to make sure that "speed up" is not the only way to say this with.
