Are devils worth 7 blood each?

Uhm ... the hammers are assumed on both sides. Removing them does not change the ratios which is what this is all about. Soul contracts yield an effective gem supply which is 150% greater ( given the input ) than the other sources.

You are adding extra factors to the equation. Barring extraneous factors, clams take 10 turns to pay themselves and soul contracts take ~ 11.5 .

Even that isn't really a great comparison because since there are so many different factors that differ between the two but assuming alchemical losses, the cost of speeding up clams beyond your natural water income, and not taking into account reduced gold, pop and research loss from speeding up blood income makes for a flawed basis of comparison.

Admittedly, it would be difficult to come up with the losses from speeding up blood production so the obvious thing to do is to not take into account rushed production on either side, in which case, clams pay for themselves faster than soul contracts.
