but I payed around and made the important variables global:

I now get 0.707_s +/- 0.1 for this program. A bit less than before. and I was wrong the first test with out the FOR 1 to 10 loop I did, should of course be 0.158 s. Sorry for the confusion I caused

If you want to run the program without having to modify it by adding the timing code, you can use TEVAL from the home screen. It's usually best to compare unmodified code. Then you don't have to worry about unintended side effects changing the timing.

Exactly, before we benchmark we need to decide what we are looking to benchmark, how we design the measurement to exactly do that and simultaneously minimize overhead the measurement functions themselves causes.
If I do TEVAL() on the whole program I measure, make list and variable memory allocations the function call etc and with a program that runs in milliseconds this overhead is quite significant.

If you want to measure how fast it actually solves the problem where the problem is given, you put the measurement points exactly around the problem solving not the other prep stuff.
