PLATO mission to find alien life is given the thumbs up

That looks like they are using both the transit method and the doppler method to look at each of these planets. I know that both methods are successful and have found each huge numbers of planets, but I wasn't aware that any individual planets had been found using both methods?

I would have thought that would cut down the useable number of targets a lot - does anyone know roughly what proportion of the known exoplanets have already been found using both methods?

Plus of course the difficulties of finding earth-size planets with the doppler method if the system also has Jupiter sise planets pulling the star a lot more.
