My attempt at applying Flynn's recipe results in a course of 7950. The items listed with a question mark indicate I am not sure I understand what he means in terms of yardage for those holes.
As David suggests, I do not think the yardage for the 18 handicapper would have increased all that much - which illustrates the strain increased driving distance has on the golf course.
‘Dividing this up into holes there would be say four short holes ranging from the mashie to the full wood shot. (190, 215, 240, 265)
‘One real three-shotter, not merely a hole somewhere over 500 yards. (650)
‘Two drive and full wood shot holes, one with a big carry on the drive as the premium with an easy entrance to the green, the other with accuracy on the drive but with the premium on a big carry for the second shot. (550, 540)
‘One drive and high spoon shot, accuracy off tee and carry to the green. (530)
‘One drive and full cleek shot to narrow entrance and slightly terraced green. (525)
‘One drive and high midiron carry to green. (490)
‘Two drive and full midiron run to green with narrow entrance. (490, 490)
‘One drive and high mashie iron carry to green. (475)
‘One drive and mashie to narrow entrance. (475)
‘One drive and mashie all carry to green. (475)
‘One drive and mashie niblik to island green. (450)
‘One drive and run up on narrow terraced green straight away. (440?)
‘One drive and runup, elbow or cape type, with premium on length of drive. (430?)
‘ The above list is not at all arbitrary but covers generally the possibilities in an eighteen hole layout.’
