Comfortably Numb PD2

This week I am going to practise the arpeggios played in the pre chorus of the song. This part happens twice during the whole song. The arpeggios are playing each notes from D,A,C and G chords separately. They are a lead guitar part which is played over the same major chords as to what the arpeggios are playing.
Here is the tabs for these arpeggios:

This is an important part of the song as it is an extra melody that helps build texture in the song and it is a very recognisable part of the song that an audience would expect to hear and to be played fluently.
I will practise this by starting of slowly and breaking each part into different sections such as learning just the first part of the A major arpeggio. This should not take me to long as there are only two positions to learn as finger position and pattern for the A and G arpeggio are the same and the positions for the D and C are the same.
I will give myself around an hour to learn this as it is a fairly simply finger pattern and isn't played overly fast.
