The data that is displayed comes from the following sources:
0.6
this is the current m5 time that is found on the wiki
time
this is the last known run time in seconds for the test
delta %
this is calculated by (("m5 test time" - "last run time") / "m5 test time") * 100
delta time
this is calculated by "m5 test time" - "last run time"
std.dev is calculated using the following python code:
# algorithm is from http://en.wikipedia.org/wiki/Algorithms_for_calculating_variance
# first pass to calculate average of all data points
for item in values:
avg = avg + item
#print avg, n, avg / n
avg = avg / n
# second pass to calculate variance
for item in values:
sum2 = sum2 + (item - avg)**2
sum1 = sum1 + (item - avg)
v = (sum2 - sum1 / n) / (n - 1)
where "values" is all run time values for the previous 7 days for the given test.
hope this helps :)
