How to do you read the alternator gauge?

The Way your gage reads, it is over charging.
How long was it running when you took the pic. Should go to center after 5 or so min's, on good battery.
Or you might have high resistance some where in the circuit.
It could be lots of common things, in the wiring, specially in the bulk head connections.
Is the batt good, how old is it. ??
Check all your connections, use dielectric grease on batt connections

Currently... I pretty much have been driving the car about 1-2 times a month on a weekend. When I first start the car it sits in the middle roughly but if I push the gas it bounces all the way to the right until I let of the accelerator. After 15 minutes maybe it will finally settled and stay fixed. Battery is a few years old, but doesn't have dielectric grease on it though.

If it is truly overcharging that would just make the battery wear out faster I assume?
