Prae This would look nice in your prospectus but deepbluediver owns the copyrights.
CoS - very simple term mathematically (and many ways to do it, for example, weighted vs unweighted) but can be misleading and confusing. An exploration CoS takes into account the probability of several terms for example, probability of Source, of Migration, of Trap, of Containment (sometimes you can also see Reservoir term but lets leave it out for simplicity).
Lets use an example, say we give each term a 70% probability - none of the terms can be 100% at exploration phase, 70% is pretty good. So, that's 70% probability each on "Source", "Migration", "Trap" and "Containment". In the most simplest math (no weighting), the overall CoS in aggregate is 0.241. (70% x 70% x 70% x 70%). So the aggregate can be low even though each term on its own is 70%. To bring the aggregate CoS down to ~0.2, all you need is to have two terms at 0.65 (65%), rest at 70% PoS if you consider only 4 parameters. In general cases where 5 parameters are considered instead of 4, then each parameter will need higher value (>0.7 or >70% probability) to bring the aggregate down to 0.2 (20%)
