Many assumptions made here.
Works for Adex,and Asin, I assume it works for other AI.
Formula assumes that the only change will be AI protocol and all other factors will remain constant.
I prefer to keep E2 at between 20-30 pg/ml, tons of science and personal as well as anecdotal results to support that, do some reading and make up your own mind.
Great thread here with various opinions and links -

Get Bloods. **Get the Sensitive Assay Test if at all possible, far more accurate** If you are happy with E level then carry on as you have, if not apply the formula and retest.
If your BW is showing different units of measure you must convert them all to the exact ones used in the formula, here is one if it does notmatch use google to find another -

I recommend BW been done at the trough of a 2 times per week injection schedule.
If you are not a math guy (I'm not) just take your time and carefully fill in the blanks. Often the answer you get will result in a tricky number that is not easy to mange perfectly in real life so some decisions need to be made. For example if you decide you need to take 2.6g/week (or 0.37/day) and that is hard to dose consider running with 0.75/EOD as the total is nearly the same per week. Or change to a different dosing sched like m/w/f if that gets you to where you need to be with simpler (physically) dosing. Run the numbers forwards and back everytime you make a change.
I will edit this post to add more tidbits as they come to mind. I'd suggest re-reading this OP every once in a while if this becomes a long thread as I will not be noting the edits. At least read it before you embark on the math journey for yourself.
Methodology and examples below....
From your BW with E2=Y as the result and E2=22 the goal, new dose would be old_dose x Y/22
“with E2= (e) as the result and E2=22 (g) the goal, new dose/week (NDW) would be old_dose (ODW) x e/22 “
Tested E2 in pg/ml = e
Goal E2 = g
Original Arimidex dose/week = ODW
Equation - ODW X e/g = NDW
Example;
Jonny Rockhard is running Xmg of TE and 250 HCG 3x/week with 1.29mg Arimidex/week (0.37 EOD) and his BW comes back at 30 his goal is 22.
ODW X e/g = NDW
1.29 x 30/22 = 1.75
This says that if everything else stays the same and JR adjusts his weekly dosage of Arimidex to 1.75mg/week(0.5/EOD) his expected future E2 level would be 22pg/ml
