This calculator attempts to assign numeric values to spellcheck results. I
don't claim that the values it assigns have any validity. Note that due to the
averaging and ranges of values, it is only ever going to give a rough check,
especially at the extreme values (most certainly fail / succeed). Paste the output of
"spellcheck fully <spellname>" in the upper box, and
click the "Process" button.
How It Works
Method 1 uses a range of 5 .. 95 with 11 steps of 9 (5, 14, 23, 32, 41, 50, 59, 68, 77, 86, 95) on a scale of 100 for each stage (5/100 for "you would most certainly fail" through 95/100 for "you would most certainly succeed")
Calculate an overall likelihood of success by multiplying the numerical per stage likelihoods of success together (eg 95/100 * 86/100 * 77/100 * 86/100 = 54,101,740/100,000,000)
Express the resulting fraction as a percentage (eg 54%)
Method 2 limits the scales to 95 for each stage (5/95 through 95/95)
Method 3 uses a range of 0 .. 100 with 11 steps of 10 (0, 10, 20 ... 90, 100) on a scale of 100 for each stage (0/100 through 100/100)
Method 4 uses the average result of the other 3 methods
