While i thank them for taking the time to tell us this information, i still don't believe this. After leveling botanist to 50 and miner to 47, i can certainly say the negative is way higher than the positive when it comes to this games RNG system.

An example would be my lastest day of mining i did for daily turn in items. 91% success chance which would leave 9% chance to fail. But i had 15% chance to HQ. Can you guess qhich one i did more of? If you guessed failed you're correct. And not just slightly, i failed atleast 3X as many times as i HQ'ed. When i finished mining, i had 11HQ and 183 NQ. Now, last i checked that doesn't seem like 15% to me. From my observation, unless you have 100% success rate, expect atleast one fail.
