Does the Web App Builder's Analysis Widget "Interpolation" tool have trouble with overlapping points in a layer?

Question

I am configuring a web app for water quality samples taken at 4 different sites along a bayou.  The point layer has 242 records a/k/a 242 point features.  However, when I run the AGO Interpolate tool (via the Analysis widget) I get an error message claiming that there have to be at least 10 points available. Interpolation procedures worked great in desktop.  Is the fact that the points are overlapping only 4 locations (same x, y's) causing a  problem in AGO? Or is this a bug?

Thanks for the feedback!

The end result was intended to be an online tool where people can view water quality features and see potential changes as more data is collected over time.  It is a school project has already spanned several years.  However this info is great to keep in mind for other uses!

Also, if you really want to use EBK with those points in ArcMap or ArcGIS Pro, you can use the Coincident Points geoprocessing environment to force the tool to use all the points and not perform any averaging.  Set the environment to INCLUDE_ALL in order to do this.  However, you should keep an eye out for artifacts in the output because including all points with a relatively few number of sample locations will very frequently cause instability and strange behavior in kriging methods.
