Offph. 120 minutes of high weight hanging. Brave soul brother. The longest I've done is 60 minutes at 5lbs, in combo with 7.5lbs for the the 10 minutes to max out length.
This is actually misinformation. If you do long-term length work like you have, yes, it's true that girth work should be spaced out after 4 hours, allowing the tissues to normalize. But if you perform short periods of high gravitational/traction force, adding contortion to lateral tissues to quickly break them, your tissues are primed to be pumped for 15 minutes to take advantage of the stressed tissues for optimal expansion.
Remember, this is not 1+ hour of intense length work and 15 minutes of pumping. This is 20 to 30 minutes of intense length work and 15 minutes of pumping routine.
Sounds like it's practically all length work from hanging and pumping. The tight cylinder will keep your entire penile shaft equalized and normal shape from base to glans, rather than a baseball bat.
