The writer is arguing that Vincent is being unfairly penalized by the use of “q.” The writer argues that it’s applied more often to Vincent than others, and is incredulous that he, far more than anyone else, apparently has a talent for landing jumps right on the quarter. The writer obviously believes it’s unfair to Vincent, and suggests it was put in place to hold back his scores (because while a Q gives full BV you get negative GOE). So the writer, comparing the “q” rule with the “Zagitova” rule that now limits the second half jump bonus to 3 jumps, sarcastically proposes that if they’re putting a rule in place to hold back his scores, they should at least name it after him.
It apparently hasn’t occurred to the writer that Vincent, who has been under rotating multiple jumps since his junior days, may actually be benefiting from the rule, since it allows for the tech panel not to ding him with the full < and reduction in BV he might have otherwise received.
