@Override

    }

    if (type.isByteCountEvent()) {
        long timeLeft = getTimeLeft();
        if (lastTimeLeft < 1 && timeLeft > 0) {
            // prime this value with a sane starting point
            lastTimeLeft = timeLeft;
        }

        // use an exponential moving average to smooth the estimate
        lastTimeLeft += 0.90 * (timeLeft - lastTimeLeft);

        out.print(String.format("\r%1$s  %2$s / %3$s  %4$s      ",
                generate(saturatedCast(round(completed + (progress.getPercentTransferred() * multiplier)))),
                humanReadableByteCount(progress.getBytesTransferred(), true),
                humanReadableByteCount(progress.getTotalBytesToTransfer(), true), fromSeconds(lastTimeLeft)));
