[mat-wg] Value of RIPEstat routing-history full-peers-seeing

Hi John,

This is due to the data aggregation that is applied when the time range
is larger than a snapshot, e.g. 12 days by default.

When you look at the Routing History widget this is shown as (more)
human readable values, https://stat.ripe.net/widget/routing-history

In the Data API output, the important value is "time_granularity", with
possible values of 12d, 2d and 8h.

The smaller the time interval ("starttime" to "endtime") for the lookup
is, the less likely you get a fractional part (other than 0).

Admittedly this is not too clear from the Data API documentation
(https://stat.ripe.net/docs/data_api#routing-history) and will be
something for the time when we revamp the documentation.

Thanks for you question!

Christian
