Thanks for this, Peter. I didn't even know a "DNA Test Misplaced" Category existed.
Considering the significant and understandable confusion test information added to an incorrect profile can cause (especially since we began displaying estimating DNA sharing percentages)--and an assumption that not even DNA Project Team Leads or Coordinators can edit test information for Open profiles unless on the trusted list--I wonder if it might be possible to have this Category be highlighted so that a banner appears in the biography box, something akin to what's done today with the "Unsourced Profiles" maintenance Category?
If the incorrect test information can't be changed by Project volunteers, I think this is a condition that readers would want to be alerted to at the top of the biography. I spent some time searching through the Categorization Project and the Profile Improvement Project, but couldn't find any reference to initiating a request like this.
The numbers won't be huge, but they don't seem to be insignificant. A quick Google search yielded 537 hits and, of the first three pages of results, I found 6 that were definitely incorrect: autosomal DNA test takers with death dates ranging from 1918 to 1960. So on average, that's 10% of 60 samples, extrapolated to about 53 profiles. The search I used only considered autosomal DNA, so I imagine there are yDNA and mtDNA tests misattributed, as well. I'll go ahead and add the "DNA Test Misplaced" Category to the ones I located.
