Yes, it most definitely matters: If I have done 1000 blocks on day 1 and
2000 blocks on day 3, then I am averaging (1000+2000)/2 = 1500 blocks per
Nope, I am averaging (1000+0+2000)/3 = 1000 blocks a day.
And the more missed days, the worse it gets - if I am only submitting once
every 7 days, that would incorrectly give me a rate 7 times as high as it
It is difficult for Excel to know what to do if there is a missing day -
if it was a graph of, for example, the growth the height of a child, it
would be a reasonable approximation to assume that if he is 100cm tall one
day and 102cm tall two days later, then he would be about 101cm tall the
But in this case, if there is a missing date, it is because no blocks
completed on that day, rather than statsbox failing to report what
happened that day.
