Does anyone have any spreadsheets or formulas to help weight the various ratings as they relate to defensive performance. For instance, like weighting ATH and/or DEF 1.5x while leaving say speed neutral? I also know the IQ matters, but how do you weight it relative to the rest of the categories, does someone just use a 100 point scale where A- to A+ is 90-99 etc? I'm really just curious if others hash something out or go more by feel.
