[bytes counter] when use EwmaSpeed ,speed and remain time calculate is wrong? about mpb HOT 4 CLOSED

Please refer to documentation of ewma lib.

TLDR
You have to pick correct weight parameter. If you choose anything than 30, ewma lib will need to collect 10 samples before any result. In your code sample you've chosen 90 and got 0 result, which means there were less than 10 samples.

@vbauerster thanks for your replay,but why this example bytes counter example it ok, params in my code is same with this. what need i do to fix my code? help~

use 0 as arg to ewma, that will default to implementation that doesn't require prerequisite samples.
