Is there anything special happening at the discontinuities or are those just locations where the number of WUs a given chunk of data is split into changes?
Rather the latter, but not quite.
It's not the data that is split into Workunits, but the "parameter space", which is the set of all possible parameter combinations a signal ("pulsar") can have, and for which we scan the data. The region of the parameter space a particular Task covers is described in the Workunit specification which your machine gets sent from the scheduler, and shows up in the command line the App gets called with when crunching a Task.
The total number of parameter-space points we need to scan increases (more or less continously) with frequency. The workunit genrator tries to split them into workunits of equal size, but it can't make the blocks it splits arbitrary small, their size also depends on the frequency.
Also too with the new algorithm other calculations and the time needed for them depend (non-linear, IIRC) on the frequency, which adds some more curvature to the "blocks" and thus the graph.

RE: Oups link to wrong page

The validated results have been purged from the DB as usual, there's one awaiting validation and one in progress.
Everything looks perfectly normal to me.
So what's the problem?
