Pressure not going away

I know this was happening last year as if you check out the below forum post's 2nd example comment from me, you will see a video of my team being in their zone after our pressure meter was almost full. We cycled in their zone for over a minute long only to find that it had gone down to about a little under 60% when they dumped it back into ours. In the main example however, I leave the AI's zone and come back about 30 seconds later to find it at 40% from 80%.

1. 80%-40% in 30 seconds offline

2. 100 - 58% in one minute.
Something seems off here....
