I truly have no need for such a thing xD I understand odds quite well, but thank you 
I cut a stone of 950 gold, it is expensive but it does not reach 7/7
Why would you pay 950 for a stone??
I wouldn’t pay that much if it came together with a Stone of chaos xD
:DDDDDDDDDDDDDDDD
no
you can use the calculator
it is calculating probability which will give you your stone much quicker than you just winging it
but the calculator is not fun
i don’t use it

Sometimes you gotta just use your intuition, especially when them reds be poppin’ at 25%
probability is different from a chance to succeed and humans can’t internalize probability
but in the end it’s entirely luck
a 9/7 rock is flipping a coin 30 times and calling every heads or tails correctly
You know it’s not xD
That would be a 10/10 stone with 0 hits xD
But close enough
9/7/0 is 16 nodes from 30
you start off from 75% so your average is 17 nodes succeding
10/10 is 20 nodes those are really rare to occur they aren’t only about you guessing correctly
That’s way too complicated for me this early in the morning.
But hey, I’m pretty sure chances are better than 9.31 e10^-10 which is fliiping a coing 30 times and calling them all xD
well a 9/7/1 allows you to guess incorrectly 5 times
That is mindblowing. I’m not even gonna bother to check that
if you pay attention while you are fasceting you will notice that your average stone is 16 nodes succeeding
the hard part is guessing where they succeed 
thats why the chance of getting a9/7/1 is 0.03%
probability is just something we can’t really comprehend
our brains are not equipped for it

My man 
There is no such thing as 50% chance lol. why would they do that. but there is tools to help you, you can try this one
Yup. And 50% = 5% in Lost Ark, so you probably don’t want my method.
I’ve cut 13 stones that were 500g each and my best two were 6/7.
i know the pain mate. used 100k, to cut a 8/6 stone on my main.
and when Artist came, i cut a 7/7 stone 1st try.
Better Pray to the RNG gods
if you try to get a 7/7 and put both 75 and 65 on the same engraving then probably not
It’s mostly intuitions sometimes my intuition is spot on sometimes it isnt.
Stone cutting is a pure RNG fest. You can make it more reliable by min maxing but at the end of the day it comes down to luck. The other day i cut a Raid Captain Ambush Stone and after 22 Hits i was sitting at Raid 10, Ambush 2 Negative 3 with 8 Hits open on Ambush alone and 25 percent🤣
At this point i just closed my eyes and hit the button on Ambush 8 Times. Sadly it turned Out to be a 10-4-3 but on the other hand it is perfectly fine for what i aimed for.
