In the screenshot below, you'll see Orange's funding is still working on me even though we have only 19 Np difference. It eventually stopped naturally after a couple ticks (can't tell you how many, I wasn't perma-connected).

Depending on how the exact coding, it is possible that the game allows funding at 19.5 or even 19.01 more NP.
