Here's a script for max accuracy when on a bike. It's the same structure as the max accuracy scripts from the table from @aanpsx, but seems to be unrelated to the walking accuracy. It's a different injection point, the offset is +2988 instead of +2974, and the value goes from 0.0 to 1.0 with 1.0 being locked on perfectly.
@aanpsx feel free to add it to your awesome table
