Of course at low tensions the difference is large. As you tighten the
cable, the cable stiffness becomes less of an influence.
I'm looking at the chart for my Penn-Tech TM-800. For the wire sizes
where it give both 1x7 and 1x19 conversion factors, such as 9/16", the
difference between the two construction types becomes vanishingly small
as you approach the 10% initial tension point, which for 9/16" is 3500 lbs.

Maybe more of the mech eng types could ring in on this one but with
quite small deflections as generated by wire tension gauges I would
expect the variations in readings from SS sailboat rigging to EHS to be
minimal and as Grant said for relative measurements used to equalize
tension the absolute value of the reading is not important only the
variation from one wire to the next.

A model with 3/16 to 9/32 wire capacity is the Loos 90 Model B, again
for 1x19 sailboat rigging. With the substantial flexibility
difference between these rope constructions it will need to be
calibrated with a dynamometer tension gauge for the EHS being
measured. Otherwise the readings are only relative, which is useful.
