Do you have any idea how many Roman swordfighting techniques are still known to this day?

Would you say that more that 100 Roman swordfighting techniques are
still known to this day? I've seen one on The History Channel. It was
a bunch of rapidly fired uppercuts done with a short sword while
covering up with a shield.

There's no web site or nothing to check out online I don't think since
I looked for them a bunch of times--not recently though.

Do you have any approximate idea of how many moves are still known to
man?
