Is the EMA implementation code in this repository wrong?

[prowontheus]

in the update_average function of EMA class in modules.py，the update step is:
old * self.beta + (1 - self.beta) * new
should it be "new * self.beta + (1 - self.beta) * old"?

[draym28]

actually, the code is correct.
the formula of EMA is (suppose the weight beta=0.9):
new = beta * old + (1-beta) * current
the new average should be "a lot of old parts + a few new parts".
