The underlying gauge component already takes a number between 0 and 1 to determine how far to rotate the dial. It’s easy enough to apply whatever algorithm I want to as long as I continue to feed the underlying component a number between 0 and 1.

Current behavior is as follows: the default settings have a target of 100 apprentice items. Ignoring “new” RKV items, 0 items displays 0%, 100 items displays the gauge at its halfway point (50%), and 200 (or more) items pegs the scale at 100%.

I’m leaning toward keeping it linear. At it’s simplest, it’s a “how many items are in your apprentice queue” meter. Weighting new radicals/kanji/vocabulary is hard enough to understand and reason about without throwing in logarithmic calculations.

Maybe a statistical approach? I could assume a normal distribution and use percentiles. That is, values within 34% of the target number (one standard deviation) are considered “normal”, more than 34% away are considered low or high.

I think value-dependent color is easy enough to introduce. I hadn’t thought of eliminating a numeric display altogether and **only** showing words, though. That’s an interesting thought.

Instead of a numeric value, I could display random vocabulary depending on the range. In addition to changing the color as discussed above, I’m thinking maybe something like the following.

Assuming a target of 100 apprentice items:

- 0 to 65 items (low): マジ？ 頑張れ 退屈
- 66 to 134 items (normal): 平気 普通 並
- 135 or more items (high): 超圧 危機 疲れ

Thoughts?
