What if the token represents a high-quality answer, but would have only been picked 80% of the time, but now it's picked 90% of the time? I'm not entirely sure

What if the token represents a high-quality answer, but would have only been picked 80% of the time, but now it's picked 90% of the time? I'm not entirely sure (haven't read the original synthID proposal), but I believe that the re-weighing is set to make both your scenarios and mine equally likely, averaging out to net Zero effect on quality.
