I read through this thinking "why doesn't Previous get assigned to
currentEncoding here? But it's because the initializer runs right after
the ctor and before the "method" returns. So really there's 3 operations
running on one line here - ctor, init, and assignment.
Has previously been discussed internally. Probably good to get this out
before the next full reprocess of scores server-side.
The multiplier here was @smoogipoo's suggested value. I'd be willing to
go lower if this is seen at too high, but it should be a round number to
make it easy for users to understand the max score available to them.
