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 On 25/04/2021 23:18, John Kristoff wrote:

The RIPEstat Data API for the Routing History call includes a key output field "full-peers-seeing". It is described this way:

The number of RIS full-feed peers that saw this route.

Often times the value is not a whole number. I'm wondering why that may be the case and how I should interpret it. Hopefully this is as good a place as any to ask the question and get an answer archived for posterity. Thanks in advance for any insight.

John
