About how many Bloods/Essence can be made at high levels?

I'm level 78 RC now and making about 500kgp/hr crafting bloods. I was just thinking about how immensely high the profits will be when I'm a higher level. I know that 2 bloods/essence won't happen but how high will it get? Will I hit 1.7? 1.5?

 

i have 99 rc and i think its 1.5 but im not completely sure

 

I'd appreciate some more input please.

 

I am 99 rcing, but haven't tried rcing bloods yet.

However, should be no more than 1.5.

 

Runes max at 1.5 before you can 2x them.

Hence, the best you'll be able to do with bloods is 1.5.
But, assuming the level to craft bloods is 77, I think the best you could get is 1.3 as the difference between 77 and 22 is about 30% of 1 to 77.
