Why is RMSE under the name “StandardDeviation” in NetMeasurements?

I wanted to calculate the RMSE of a neural network on the validation set to get an idea of its performance compared to other hyperparameters.

It took a while for me to realise that RMSE is just under the name “StandardDeviation” in NetMeasurements. If I’m not wrong then it seems this could cause a bit of confusion.
