It shouldn't. I've been playing with the adjustable insertees for a while (along with the loaders) and have had no issues. Recipies look to be adjusted for use with Bob logistics when installed.
Is there a specific compatibility concern you're thinking about?
No, you just wrote that Bob will have 3.75, I just clarified which Bob will have 3.75, I use Bob's adjustable inserts only and the Pyanodons Modpack mods, so I will wait for updates when they become 7.5 per second.
There were no conflicts with Bob's adjustable inserts.
