math in geek window

I’d like to suggest the ability to perform basic maths on the macros that can be selected for display in the geek window.

The reason i’d find this useful is that I use the geek window as an overlay for streaming/recording my performance in rhythm games. In my particular case, I want to show meaningful statistics such as the average keypresses per second per FINGER.

Essentially, I want to be able to have an additional line in the following example that would list the keys/sec divided by 4 to correspond with the 4 keys in the game.

If this was implemented, I’d imagine that the maths could be done in a normal expression such as this:
