Additional Info:
Seems like you can only the effect the event points by changing your own points.
What i mean by this is, let's say you already have 632/2000 Bombardment Hits but you yourself hasn't contributed to this yet. So if you wanna increase bombardment hits, you need to search Float 0, then use bombardment let's say you hit 2, then refine to Float 2, then hit once again (say 2 more), then refine to Float 4. Then you'll get one value at Float 4 then swap this to 2000 to get 2000/2000 Bombardment hits. Freeze and Save progress.
You can do this with others also. (You can only search for the amount you contributed rather than the current progress in event.
