I think the title speaks for itself. It'd be nice if you coul read the average Energy/tick going in and out of a block per specified number of second/s. Could also work for fluids and items (either filter the item/fluid you wanna observe the flow of or take all items/fluids going in/out into account).

Example:
[Avg. RF/tick in per 2s: 1234RF]
[Avg. RF/tick out per 2s: 0RF]

It may be possible for some blocks. but not all. However, I'm sure I could do a total in/out for one. As in I wouldn only know the net transfer e.g. Transfer: -50 rf/t so it would tell you if it's outputting or inputting but wouldn't necessarily have numbers for each if that makes sense.

Sorry I thought you only meant Energy for some reason.... i like this idea :)
