I, like many genealogists, find that I have many ancestors in common with many of my cousins. Multiple common ancestors increases the relationship common used, like first, 2nd 3rd cousin, etc. When comparing DNA results, we almost always have a much higher CM match than what would be expected for the closest relationship we share. The coefficient of relationship takes the multiple common ancestors in consideration, an so produces a numerical value more representative of the actual relationship, than does the DNA value. When used in conjunction with DNA numbers, it more clearly depicts the relationship. The Coefficient of Relationship for two individuals can be calculated by "hand". All that is needed is all of the common ancestors, and the "paths" from each ancestor to each of the individuals. RM produces this information with it's relationship calculation. It woul seem that given the required data available witht eh relationship calculator, RM (or an SQLite program) could produce the Coefficient. I've requested this of RM (years ago), but with no response. So, I ecide to request it here.
