Intermittent convergence estimate failures #7
Description
The same set of data points can lead to different estimates of the convergence rate, which sometimes leads to tests failing:
- Failure: https://ci.appveyor.com/project/jagot/compactbases-jl/builds/33863946/job/4hwakx40umwhundm#L272
- Success: https://ci.appveyor.com/project/jagot/compactbases-jl/builds/33756833/job/u7xqcq2wugkb0a53#L272
It does not seem to be dependent on architecture or Julia version, e.g. a recent failure on Mac, nightly:
