Probability is not accutare

After picking up gathering professions and crafting professions I keep feeling that the probabilities are not really what is shown in the screen.

For crafting, I keep failing HQ with a probability of success of over 90% and keep succeeding on those with less than 10%. Tried HQ chance of 10% and succeeded 3 times out of 5 while I failed all 5 attempts on 90%(Steel Ingots). I know it's a small sample, and I will do larger scale tests later on.

Same thing goes for crafter skills and gatherer percentages.

The closest feel is like playing Fire Emblem where anything over 50% would always hit and anything below 50% would always miss, but with a square enix touch.

It is very stressing because I know that if it's not 100% I am guaranteed that whatever I am up to will fail.

Anyone else has had these feeling that probabilities are not accurate?

Edit:Just did 20 more tries with steel ingots, at around 85%~90% i got only about 8 of them to HQ. It is as if they will punish you if you do not manage to get a 100%.

The probabilities do seem a bit off when you consider a large number of items being made. I just gathered up a bunch of copper and tin ore this morning before work. I then made as many HQ bronze bars as I could (50 bars total). All the 100% attempts resulted in HQ bars. Out of all the bars I only got to 71% (about 20) , I only made one HQ. I got about 5 to only 18%, and one of them became HQ. It seems the percentages are off in the middle of the scale.
