On the other hand, both 90 days off and 30 days off are both still a very long time before an event happens.

It's going to highly depend on the type of event. But it's not surprising to me that there will often not be much difference, because the main factors affecting the event might not really start to be known until just a few days in advance.

Which really makes me wonder about in which categories our prediction markets most useful at a timeframe of months, versus which categories are most useful at a timeframe of days.
