Lengthen Data Retention Period for Score Changes

Please reverse the 90-day data retention policy for Score changes and add them to the category of ativities retained for 25 months. I frequently find myself in the position of being asked how a person attained a certain score and am unable to answer because the data is missing. Moreover, 90 days is simply too short a time period to assess the efficacy of a given scoring schema. For companies with long sales cycles, especially, it's easy for it to take longer than 90 days for a person to score enough points to become an MQL and be passed to sales. And when the data disappears it's impossible to track the path to MQL and determine if the scoring model is working as intended. Please change course and retain score changes for the longer time period!
