Healing potion calculation

[hcobb]

First hire a typical Healer: ST 6 DX 15 IQ 14 for $100 a week, plus $50 in living costs by ITL 58
Then rent a lab ($150 per week, plus $50 for materials) ITL 145
Pay out $1070 in common materials each week
And risk an average of $73 in explosion and healing costs

For a net cost each week of $1493

The payout is $1500 but this is only 95.37% of the time so net gain is $1431

I.e. you lose an average of $62 a week, under the best possible conditions.
