Nick,
Thanks for book details ...I must see if I can locate it and have a scan ....
The approaches come down to two main considerations -
(a) prop installations lend themselves to power gauges of whatever sort ..and it is lovely if you have a couple of multi-thousand HP fans either side .. memories ... jets use thrust gauges, usually EPR or N1 presentation or similar.
The performance, however, is still a matter of what thrust the installation can push into the airflow, regardless of how the thrust is obtained.
(b) the sums for jets and pistons are much simpler than for turboprops.
Can't comment on the pictures in the book without seeing them .. if I can locate it I might venture a comment or two ...
