I run an 11-28 8 speed with 44-38-28. This gives a practica; great range of gears for commuting/touring with low enough gears for most Scottish hills.
I don't think it's ever useful to try to use gear charts as often there is too much double changing and duplication. I look at mine as 3 sets of 4 choices , outer 4 rear with the 44, middle 4 with the 38 and inner 4 with 28.
I spin out of the tp one at 30plus which is fast enough, but or most touring etc I have a good spread with good chainline.
With the chart you've given us remember that chainline prevents you from using extremes.
