I agree one more Jackson ought not to be a deal-breaker. However, there are two sides to every story. CP/EPM customers may earn more $ than non CP/EPM providers? CP/EPM customers have their choices on how they want to spend their $. Likewise with non CP/EPM customers have their choices how to spend their $.
ALL customers have their choices how they want to spend $. At the same time, CP/EPM may want to reduce customer base by increasing rate? We do not know their Jackson increase justification. Don't ask why. Either go for it and agree to their terms, or seek elsewhere.
