i think in this case, when you are taking 3 or 4 years' average, how can you get it for first year or second year or third year. you will have to start getting it after 2-3 years,
example: year value 3 years'moving average 1 100 - 2 110 - 3 90 100 4 95 98.3 5 105 96.7
now, if you want to take 3 years' average, how will you calculate it for for first 2 years. so, you need to leave first 2 rows blank.
