Comment (by pastly):

 There's no parameter that directly controls the frequency with which sbws
 will scan an arbitrary relay. If you want to increase (or decrease) how
 often sbws gets around to scanning relay Foo, then you can

 - increase (or decrease) the number of measurement threads (def: 3, I use
 6 when I test sbws)
 - decrease (or increase) the number of downloads to make per measurement
 (def: 10, I leave alone)
 - decrease (or increase) the duration a download must be in order to be
 considered valid (def:

 documented here])

 If you're against changing those parameters and still can't manage to
 accumulate the desired number of measurements for relay Foo within the
 validity period, then you can increase the validity period.

 In the name of the added code complexity, I'm against adding a notion to
 the prioritizer that says it should aim for making a measurement for relay
 Foo every X hours. Or that measurements should be performed differently
 when we have a lot of "catching up" to do.
