So it actually works slightly differently on the server. The bank trick does not work, sadly, and the lobby trick has some additional steps. If you feed to 5/100 and then you lobby and then you switch blocks, it will revert to 4/100. As JADE pointed out, if you just lobby each time, it will appear to work but when you eventually switch blocks, it will revert to what it "should have" been as that is what syncs the client with the server.
Since this trick is very time consuming, I would not recommend it for long periods of feeding, but it can be useful if you need to do it only a handful of times (less than 20).
