My guild periodically has issues where multiple players deploy in a phase, but the numbers are delayed to show up. This has caused us to have players over-deploy in zones that already reached the goal (be it 2 or 3 stars).
1. improve the server technology to refresh the display more continuously
2. Require each player's client to pull a fresh status whenever they open the TB (not happening right now)
3. Add a "manual refresh" button similar to what exists on raids, so a player who is monitoring the GP totals on a zone can refresh more quickly.
