Hypnodisc couldn't gash 101 because the flywheel wasn't working 100% for most of that battle - not to mention Hypno's flywheel was a lot more potent in Series 4 and knocked the panels off, rather than gashed them. I think the most accurate comparison is Shunt - whose axe was certainly more powerful than Dominator's and still it couldn't penetrate V-Max.
