Does the Daily Peak Bandwidth Mean the Upstream Bandwidth or Downstream Bandwidth?

If you choose to be billed by daily peak bandwidth, downstream bandwidth is billed by default: Daily peak bandwidth = Livestream bitrate x Peak number of concurrent viewers.

If the ratio between the number of livestreams and number of viewers is greater than 1:50, both downstream and upstream bandwidth is billed: Daily peak bandwidth = Livestream bitrate x Number of livestreams.
