So unless the +10% chance to the rest of the benefits makes it up, I think you are right. Especially since we probably aren't intending to do phase 6 any time soon.
Phase 6 of Alloys is something I'm still unsure about to be honest. Its half as STU expensive now, and it doesn't give the cost reductions that the previous phases did, but it gives a bonus to tib income, and if it only increased things by 90 RpT that would pay back the STU spent to get it. Plus the income boost would be nothing to scoff at.
If instead of increasing Tiberium Mining it increases our Maintenance Reductions that wouldn't refund the STU, but the text says '(Improves Tib mining efficiency)' not maintenance reductions so...
