Game Mechanics: crafting success rate

[Silvermink]

Has anyone else noticed a very low chance of failing crafting items? On over 1500 crafting combines I am convinced that the success rate is off. This applies both to very trivial combines (5% base failure rate) and items that are about 50% success rate. I seem to be failing about half as often on the 50% items and went 200/200 on trivial items. While not statistically impossible, my luck has never been that good.

PS: If this is considered an exploit, please move to the proper topic. I posted here because I wanted to see if others had similar experiences. I have asked in OOC but never gotten a response from a crafter.
