Discussion: start your watch

Before you start running your warmup?
I haven't really found a prob with my suunto, but my garmin used to have a sh!t in the first 3 k or so if i wasn't still while it satellite fixed.
If you start it while still, and then do your warmup, you've got the best chance of it being stable by the time you do your interval?

Mine still has a sh!tter for the first km or so mainly because my runs normally start underneath a huge overpass...
