Noctilux: $2,500 Summicron: $795
ASA 100: $2.19 ASA 400: $2.49
1/60s: $0 1/15s: $0
$ flash: $50 $$ flash: $500

= $2,552.19 = $1,297.49
Let me add one:
Two stops! That a difference of $1,254.70!!
In fairness though, I should admit that my analysis is incomplete. If
we assume an hourly rate of $25/h, that translates into $25/3600 = 0.69
cents/second. Thus, with the Nocti, the exposure costs 0.0115 cents,
while with the 'cron it costs a whopping 0.046 cents. Now, that may
not seem like much, but add it up over 50,000 exposures and your
talking about 1,725 cents which is, of course, how the professional
photographer justifies the difference in purchasing price of the two
lenses.
