The first deposit I mined seemed to have the expected proportion of dull green to neon green uranium but then I went south just a little bit and found another big patch of uranium. So far this one has produced about 4 chunks of the bright green stuff after mining maybe 10,000. I have about 18 centrifuge working for more than an 2 hours with no modules. It would be kind of cool if this is how it is, but its also annoying and not like the rest of the game or any game at all. I would expect that all deposits would yield about the same ratio of 1 bright green in every 140 chunks mined.

So my question is have I done something stupid or is it really like this? Version .16

Source of ore have nothing to do with chance of u235 output. I seems you are just unlucky.
Try to set up Kovarex enrichment, you do not have to worry about chances with it.

The output is determined upon processing by RNG. You just have bad karma
