Tall people (like me) want to get measured later in the day so this early morning stretch does not NPQ them.
or you could do what i did, i was over the sitting height limit by almost 3/4 inch for everything except p-3's so i just jumped off of a 2 foot box for about four hours the day before, went in and got remeasured, fit everything now (my buttock knee length, a whole different matter). either way, i fit and now i can fly
