Woa,
Real S. Shady!
It is not unusual to turn the aircraft round in 17 minutes where the ground handling services are slick
that'd only be where the ground handling services are slick
and the load factor was either
real slim or
real sick 
I am all for a bit of well motivated teamwork, but I think you are getting a little carried away with your optimism
You'd certainly amaze me if I saw you doing chocks in to chocks out in 17 with any meaningful load e.g. 160<pax<=189. Totally impossible for all reasonable intents and purposes I'd say.
As for your claim that 25 mins therefore isn't stressful, well on a good day, with a good team, and no detracting factors, and not counting a healthy background level of team adrenalin, endorphins and sweaty armpits all round, and on the basis that practice makes perfect, I'd just about allow that
, but how many
real days actually fit the ideal on every sector
? It's that robbing of Peter to pay Paul that surely creates the stress?
And then before you know it,
ding! (oops!)
