Thanks for making this change! If I may offer a humble solution that will save you time tuning or re-tuning the timing of TBs going forward
1) Launch TB's once per week with a 6 day timer.
2) Allow guilds to mark a phase as complete and reset their toons at will.
3) Rewards are distributed when the 6 phases are done, OR the 6 day timer expires, whichever comes first.
4) the next TB starts.
If guilds burn all toons and finish phases fast, they can run through the full 6 phase cycle without waiting. On the other hand, if they need a little extra time to get coordinated, they can hold off reseting longer as needed. This flexibility leaves what to do in the guilds hands and requires no further analysis or resources from CG freeing you to continue your good work.
As a bonus this would be particularly valuable when members are traveling or ill.
