How much rodinal with 8x10 ilford Delta 100 in jobo 3005 expert drum

Hi guys,

Do any of you know how much ml of working solution I will need "Per 8x10 sheet" to develop ilford Delta 100 using Agfa rodinal?

According to statements by AGFA people before they went out of business: 10ml. According to many users of 35mm film: 5ml, + or -.

I once read somewhere that people were using 75 ml of working solution (including water) for each sheet of 4x5. Given that 8x10 has 4 times the surface area, I would think that I would need almost 4 times the 4x5 volume of working solution. I may of course be wrong. That what experimentation is all about.
