Using average of previous average and the next value is highly imprecise. E.g. for values 20, 20, 20, 180 it would result in /average/ of 100 (instead of 60). Fix it by storing & using an info of how many samples were used for the previous calculation. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
