Hey look I made a template thingy!
Special Upgrade analysis: TLDR; When you have rank 1 everything, you're gonna use red, except maybe for staff.
Expectation of stones: Given the success rates of the stones, and the fact that a failure decreases the current level by one (except +5 to +6 which destroys the item), we can calculate the expected number of stones to reach each new level. For example, when trying for 2 to 3, we will either decrease to 1 or increase to 3. Hence we require the number of stones to get to +2, plus the expected number of stones to get to +2 from +1 times the number of expected failures, plus one stone for a success.
|Level||Rate||Expected number of attempts||Total Stones|
|0 to 1||100%||1||1|
|1 to 2||50%||2||1 + 1 + 1|
|2 to 3||50%||2||3 + 3 + 1|
|3 to 4||45%||20/9||7 + (11/9)(7) + 1 = 16 + 5/9|
|4 to 5||45%||20/9||(16+5/9) + (11/9)(16+5/9) + 1 = 34 + 1/9|
|5 to 6||45%||20/9||(34+1/9) + (11/9)(34+1/9) + 1 = 69 + 2/9|
However, these are only good averages across a very large number of weapons (trillions of weapons). For perspective (per a recent discussion with some guy who likes python), about 50% weapons will use less than 21 stones and about 80% of weapons will use less than 45 stones.
Thus, you can consider yourself "unlucky" if you require more than 40 stones to get to +5 and you can consider yourself "lucky" if you require less than 20 stones to get to +5.
