Weigh in between 170.1 and 182.0 (weigh in at the 182 weight class).
"Bump up" the 1 allowed weight to wrestle in the 195 weight class.
Since you weighed in at one of the 2 allowed weight classes on the decent plan for THAT WEEK, you maintain elligibility to wrestle at 170.
Also, not positive about this, but it is my understanding that if you officially weigh in, you can be locked in at a higher weight class, even if you don't actually wrestle. Refs?
