Äh, I´ve talked above about, to start in your rig the stirring FIRST.
I have no experience with distillations, but I would heat it up slow straight proportional.
(e.g. 1 or 2 °C in a minute or longer)
Please critisize me, if I see something wrong...
Instead of constantly changing glassware, I recommend you try this technique, in order to test/seperate your fractions.

Of course, the simplest way to the purest safole is to double freeze. ;)
Good idea, if the flasks are big enough to contain the whole fractions..
You can also use, without breaking the vacuum, a fraction cutter.
A fraction cutter is shown in post:
