[@EricLeePiano]

Very good explanation! Thanks.

[@iqrayounis9471]

for the data points for the miracle grow table you missed one value which is another 9 ,then n-1 would be 7 as there are 8 values -1. whereas in your table there was only 7 values -1 =6. That's why i got incorrect value but thank you for explaining anyways.

do we always draw 2SM, when do we draw 1SM ?

[@jarinmaisha3158]

I have a similar question, why not any other number but 2 Sm? And also could you please explain if you found your answer?

This is incredibly lengthy and incredibly boring.
