I am less than keen at the idea of rolling D100 30 times to generate stats, so below is a formulaic method that achieves roughly the same results:
Roll D100 for each stat, and read the results as two numbers, a HIGH ROLL & LOW ROLL by reversing the tens and units on the roll. Then find the mid-point between the two numbers with the following formula ((HIGH ROLL-LOW ROLL)/2)+LOW ROLL round up. This new number is the Temp, and the HIGH ROLL is the Pot.
/For example a roll of 7 & 4 becomes LOW ROLL: 47 and HIGH ROLL: 74. This produces a Temp of 61 and a Potential of 74.
A small complication is doubles. My first instinct is to ignore them. There are plenty of other ways to get rid of them, though, if you want (simplest: re-roll, more complicated, swap one number for a 0 so treat 88 as 08 & 80).
There is a chance of rolling 01, so again, re-roll is an option, or ignore and rely on swaps to get rid of the aberrant stat.
