And it takes at least 0.6s from my testing before the server acknowledged what I'm doing is illegal, for an action that is illegal 100% of the time. If it was possible to 'force an update', I'd expect to get the result of my illegal action back earlier, but this is clearly not the case. Try it yourself. Start with autorun and try to reliably stop your spell by doing anything you want. There's no skill factor because what you're doing is 100% illegal to begin with, so all you're doing is trying to tell the server 'hey look this is impossible!'. The time it takes you to interrupt the spell represents exactly how far behind the server you are.
