we were going to reduce the 2 hour drift to 15 minutes, then i brazenly chose 30 seconds. 2 * 15 is 30 seconds which is our blocktime. we decided not to go with that as blocktimes do vary a bit.
we've done a complete rewrite and will be pushing it shortly and contacting our pool ops and exchanges.
i love seeing so many people who aren't even involved in verge talking about it though ;]
