Wait Function

[cabbagekid2]

We were wondering how the wait function works (the clock timer in periodic task). Initially we thought that the clock time is the minimum time that the while loop will wait to execute the next cycle (it will either be this time or the actual time it takes to execute all the code in the while loop - which ever is longer). However, using the elapsed time vi we see that even though we set the wait to 10ms the actual time shown in elapsed time the time is less than this (see screenshot it shows 2ms).

Can anyone clarify what is going on here? Thanks.
