I’ve noticed support does not always remove the “recommitted” tag when a derailment is not legit.
Since this tag indicated that you derailed and are now “recommitted,” it shouldn’t be there if the derailment was not legit, and support should always remove it when you tell them that a derailment was not legit.
Some people want this there because they want to make a note of their non-legitimate derailments. If they derail and they’re sick, for instance, they want to have that on the graph to show where they deviated from the original plan, even if it doesn’t count as a legitimate derailment or cost them money, so sometimes it’s better to err on the side of not messing with that datapoint, since people can delete it themselves, but can’t create it themselves.
