If you are a trucking company would you buy the truck that costs more and need more fuel but drive on the road all the time, making money. And if something is defective you have very good customer service.
Or the one that is cheaper, needs less fuel but you have troubles all the time, you have to argue with the customer service about very cheap spare parts even if you bought hunderts of trucks from them....
...

As for your analogy....
That's so flawed that I don't even know where to begin....
Since 66 is the LCM...

	Unit Cost	Power Usage	TH/s	Power/TH	(kWh) cost USD	Yearly Power Cost/TH	Yearly Power Cost @ 66TH	Purchase Cost for 66TH
A7	$1,222.29	1,000.00	6	166.67	$0.10	$146.39	$9,661.87	$13,445.19
S9	$1,232.00	1,185.80	11	107.80	$0.10	$94.67	$6,248.40	$7,392.00

Edit: purchase price alone, you could buy 11 S9s (not counting the 1 that the power cost difference makes), throw 5 in the trash (having never used them) and still save $.

your price is off on the a7 they are $888.00 before shipping not 1,222.29

I paid 2,032 for 2 with 1 controller so if you use 1016 not 1222.29 you total for 11 = 11176 that counts shipping and gives you 5 rasp pi's

my last s9 was 60 to ship so 1232 + 60 = 1292 x 6 = 7752

so s9 = 7752

avalon 7 = 11,176

if 1 s9 breaks that is 16.667% loss
if 0 A7 breaks that is 0% loss

so 7752 x 1.16667 = 9044 act cost of the s9 not 7752

so compare 9044 to 11,176

next if the old s9 is really 83% block luck

9044 x 1.16667 = 10551 is what 66th of old s9 costs you vs 11,176

power you did at 10 cents do it at 5 cents

a7 = 4831 not 9661
s9 = 3124 not 6248

So this would be a lot closer to realty for people that can do 66th of gear and purchased the old s9's

cost of the old s9's were a lot higher then the numbers used here. but some of the time blocks were 25 not 12.5

But that just numbers.

So if you want to prove a point at least use the right prices for the avalon 7's

it still shows that s9's are better not a lot but still better
