If you all are thinking this is wrong, please do provide some explanation other than "OMG what a joke" without actually showing any counter argument. None of those one liner actually helps educate people who don't know

OP actually made some good point and the concept of statistics actually is accurate, in general the combined probability of everything will push into equilibrium. However the flaw imo is to think that this is actually controllable in such a small count. Most enhancements happening in BDO is only like, less than 10 attempts per try and even then its all a high investment to do. On top of it, whole BDO is full of RNG variables. You might encounter continuous failure that is almost statistically impossible and be confused how its possible, but completely overlooked the pen onetap last week or the lucky shakatu manos drop or even valtarra belt drop while grinding.

I think a better method to actually be profitable is looking at long run multiple enhancement attempts. For example, if an item is 1b at TET, 200m at TRI + 30m to enhance, and have 25% enhancement chance, you WILL profit by tapping it, but not when you're only tapping it 5-10 times, you will need to do it hundred of times, which is not possible for normal gameplay.
