Lucky you. This has not been my experience. I tuned on stage yesterday. 
Called ahead, had stage manager open piano and turn on lights, started tuning 
20 minutes later. Shouldn't have rushed it, don't usually. Piano was still 
creeping after another 20 minutes, three cents in tenor. This is way too 
much. Seemed to have pretty much settled down after a total of about 45 
minutes. I'm going to wait longer today, as usual. Each stage I tune on has 
different effects from the lights, different time to stability.
