Easy answer: start from say 10, so your power function goes like 10, 11, 12 ...

Advanced answer: linear functions aren't so great for things like powers, where you're interested in the relative difference between powers. For example, power 100 should be noticeably different to power 99, even though the linear difference is just 1%, barely noticeable. Instead you should start with something like an exponential function, Don't be intimidated by the notation, it just means a function where every step is a constant factor up or down. You see this crop up in a lot of places, such as exp required for next level up, the amplitude from volume knobs, chance-to-hit formulas etc.

Instead you should start with something like a geometric series, which means a function where every step is a constant factor up or down.
