I didn't mean Lower the 5 "Time Limit". I meant lower the "Recharge Time" of Kamui itself, as in the time he'll have to wait before being able to use Kamui again after using up the initial 5 minutes. We were never told how long it takes before its usable again after those 5 minutes with one eye.

We don't know how long he has to wait for Kamui to recharge so he can use it again after those 5 minutes are up. It's possible he must use up all 5 Minutes (300 seconds) before he has to wait for Kamui to recharge, but we don't know, leaving room for interpretation.

Hashi cells shorten the Recharge Time of Kotoamatsukami (from 3,650 Days (10 Years) to 1 Day), so the same rule could apply to Kamui as well, since its an MS technique.

Anyway, even if that isn't the case, Obito should be able to use 10 minutes worth of intangibility with both eyes, since they are only at half power when used apart, and that much is supported by the manga.
