Raising the Tower Strength for State Champs?

[iBleedBlue48]

As the season progresses, TOWERS may become fortified to increase their starting STRENGTH. While the starting STRENGTH of a TOWER will not change between weeks of Regional or District Competition play, the starting STRENGTH of a TOWER may be changed for District Championship and/or FIRST Championship play. Teams will be notified of changes in the starting STRENGTH of a TOWER no later than the scheduled Team Update prior to the date of the event.

District Championships are fast approaching and 2 districts have even finished all of their district qualifying events. As we prepare for our District Championships, I'm sure everybody is wondering what the new tower strength is going to be. At many events, capturing is becoming very easy for some of the top teams, and some events are even seeing towers with a strength of as low as -10. How much will FIRST raise the tower strength to make capturing the tower a very difficult task once again?
