The ten months is not arbitrary...it is there because the real US conducts its census every 10 years, and years IRL = months on the fantasy board. But the membership of the fantasy board changes enough that more a more frequent census might be appropriate.
I agree with this amendment...but maybe we could just say the geographic integrity is a important factor to consider when drawing districts, rather than placing limits. After all, you can gerrymander things pretty badly and still maintain continuity (e.g. a district of ID, UT, CO, KS, MO, TN, GA, and FL), and that sort of thing should be look on suspiciously.
That's why we have gubernatorial elections... if you don't like your officials, boot 'em out
Anyway, I'm sure any suggestion to do that would be ridiculed by the other governors.
