I was thinking more about something that both would keep security the way it's now but also shorten the powerdown.

I.e. 1/13th every week for 4 weeks the way it's now.

After 30 days you can't recover your funds anymore anyway with account recovery

So the 5th week of the regular powerdown would instead get you everything/the rest liquid.

so ~7.7% weekly for the first 4 weeks, then the rest ~70% on the 5th week.

If you've already lost it after 30 days it doesn't make a difference than the hacker gets everything all at once past the point of no return.
