question about short term drift test of Agilent 3458A

[analogRF]

I want to do the short term drift test (as per service note 18A) using the CAL? 72 but I cannot keep the unit running 24/7 for 7-10 days.
I can run it for like 5-6 hours per day.
Is it ok to run it say 6 hours a day and get the temp and cal?72 after an ACAL at the end of each day and then turn it off and repeat the next day to
gather enough data? or is it mandatory to run the unit 24/7?
