get-network-wireless-usage-history - incorrect units in API/documentation?

[david_n_m_bond]

The get-network-wireless-usage-history endpoint, documented here: https://developer.cisco.com/meraki/api-v1/get-network-wireless-usage-history/

...indicates that the units are kbps.  Is this right, or is it total transferred KB?  If kbps, is this mean or max?  If it's mean, can the number of KB be inferred from the time range as dataVolume = dataRate x time?

Thanks!
