While Env is rolling, you want to build into Anticipation as much as you can without potentially losing CPs. You will need to play at high energy and Anticipation to avoid dropping Env when you need to refresh Rupture.
I also save my Vanish/Prep until I see I won't be able to maintain both Rupture and Env full time. This nets you "free" CPs when you need them; using it before then will just result in more Env clipping, energy capping, or CP capping.
Also note that haste builds will have higher Env uptime, but Env will do more damage for mastery builds. The gap isn't as large as the one you're describing though. It's probably just a matter of utilizing your SB and Vanish/Prep better while playing off Anticipation and at high energy more.
Hopefully this makes some sense. It's a flow that I've developed an intuition for and have trouble describing.
