Those numbers are a bit wrong IMO. Clinical studies show test-e and -c in healthy young subjects has a half-life of 5-8 days, and my own labs have shown on 3 occasions that it's 5.5 days in me for test-e. This is "freefall" decay outside of any peaks from fresh pins, and for a post-pin measurement I'd have to add on 24 hrs for peak to hit... so it's 6.5 days if I'm measuring from the pin. Here are some charts showing similar results -- 5 or 7 days post-pin:

I dunno how the guys in your linked table are coming up with "8-10" or how others get even nuttier "12-14" results but I can't find any studies showing that.
Aromatization typically affects only a fraction of a % of the T in your system so you'd never notice a "drainage" effect on lab levels. Normal ratios of T:E2 will be 200:1 or 500:1, something like that.
The only significant effect E2 has (aside from moobs, etc) is that your HPTA will down-regulate in reaction to those high E2 levels so primary T production will plummet. Exogenous T nullifies that HPTA concern since it's already shut down. For juicers, an AI isn't going to budge your T.
