If you've actually used T1 bombers before you will know it basically takes all of your APM to have a single T1 bomber fire every 5 seconds on a moving target. I don't think I have ever seen anyone hoverbomb with multiple T1 bombers so they fire once every 5 seconds, which likely means that that is practically impossible.
Asking for a DPS increase for the jester based on the hypothetical maximum DPS of a T1 bomber means you're either intentionally cherrypicking fallacious stats or you've just completely forgotten how bombers fundamentally work.
