Exclude first two and last two turns from IQ average

Turn monitor shows Ski IQ for each turn but overall IQ is based on an average of all turns. Whenever I finish a run it is usually at a lift queue or due to other people. Turn monitor shows that my last two turns, certainly my last one, have very low IQs and therefore impact upon my overall score. I don’t think the first one or two turns are included. In any event my suggestion would be that the first and last two turns are excluded from the average score.
