I’m still running tests in different scenarios to try and find a problem. So far I have done a few million tests with all combinations of shards and glyphs. It’s a lot of tests. I’m getting near perfect distributions with automated testing. I’ve been running manual tests in the live version and so far after 200 crafts, I’m within 2% of theoretical. I did have several fractures at 85%+ estimated success rate. I’m not done looking at it but initial results indicate the displayed chance for success is accurate.
This isn’t where this conversation ends though. We are still expanding the crafting system and it will be getting updates that improve the functionality and feel of this fracturing system.
