Dear Freya, I believe I provided a fair and balanced assessment what the method can and can not provide. Whether this is "convincing", or in other words good enough for your purpose, is not up to me to decide.

For most pratical purposes, the method described in [1] as good as you can get. Make sure that the EOG channel are close to the eyes so that it does not pick up to much EEG activity. If you want to improve on that, you might try some subspace methods (ICA, PCA, etc.) but you need a large number of electrodes (at least 20, probably more) in order to identify a 3rd spatial EOG component. Concering the 1/f analysis, you should take into account that this might be conflated by other artifact sources,...

Hello Freya, Concering 1): I'm not using EEGLAB so I can not comment on this. do you mean "rtsBCI" [2] (no rstBCI) which is the Matlab/Simulink-based recording from Reinhard Scherer.? It that case, you might need to add simulink block that multiplies the sampling vector with a suitable, sparse, re-referencing matrix. Concering 2). Technically, you can. The question is about the resulting signal quality. (i), you will capture and reduce only 1 spatial EOG components. (ii), which reference electrode...
