μ is lowercase mu in the Greek alphabet and denotes micro. The units used here are microseconds and are far more accurate than milliseconds. 1 microsecond = 0.000001 seconds whereas 1 millisecond = 0.001 seconds. It doesn’t take much brainpower to figure out the units used here and even if you’ve never seen them before Google exists.
Just asking, why would you need a module script for the bindable event?
I always use a script and it works good, I find the module script way too hard to understand, can anyone tell me that in simple words?
