Proportions + Devnull + special ingredients = Derek's Mod Gold

[Tnarg]

I'm curious on how the luck trait applies to Derek's Mod. Yes, half the chance for bad events; but, half the chance for good events too, or double? On that note what are the frequency rates for medium or high catastrophy frequencies. 1 out of 20 for high and something like 1 out of 50 for medium? I have only once encountered a catastrophic event, and I was playing at a medium rate for the most part.

Then on to technology research rate. Am I going to be looking at impossibly long periods of research ie, 10-20 years the further I advanced, or would you recomend just playing with average tech cost.

I have been reading some of the previous Posts, and it looks like mounted missles are no good to use. Am I correct on that assumption? Thanks
