Recently, I have been trying to build a stopwatch for Nspire with Lua. However, when run, it obviously slows down. My program used a timer with 0.1 seconds, but I changed it so it had a timer with 0.09 seconds. That was still a bit slow, but 0.08 seconds is a bit too fast. The timer can't do anything with less than 0.01 as experimentation and the Inspired Lua wiki have shown.

Is there any way the timer could be fixed so it is more accurate? Or is there another way to do this?

P.S. My program uses tenths of a second, not hundredths or thousandths.
