Ra table updates are filtered. This is a weighting factor that takes a certain percentage of the previous Ra table value, and the remaining percentage comes from the newest calculated Ra value. This prevents resistances in the Ra table from changing quickly.
Ra = (Ra_old × Ra Filter + Ra_new × (1000 – Ra Filter )) ÷ 1000
Ra Filter is normally set to 800 (80% previous Ra value plus 20% learned Ra value to form new Ra value).
