Also appears I have misunderstood what D C R Hunt was saying too. -
"The tensions on a drive side are more than double that as on the
non-drive side and wheelbuilders and manufacturers have been creative in their solutions to
this problem.
Sometimes people opt for twice as many spokes on the drive side. Quality rims normally
have an allocated direction so this can be an inelegant solution with spokes facing the wrong
way in the rim. Another solution which I sometimes use is to have different spokes on the
drive side to the non-drive side.The non-drive side will commonly use the same spokes as used on the front wheel.
The drive side will have heavier duty spokes and importantly spokes with less flex.
This means that the spokes flex more evenly on both drive side and non-drive side.
A light duty build could use Sapim Laser spokes for the front and non-drive side and Sapim Race for the drive side.
Heavier duty could be Sapim Race for front and non-drive side and Sapim Strong for the drive side.
You could also use D-Light spokes with Race spokes or Laser spokes to achieve similar slightly varying results.
Many wheelbuilders neglect such detail, although it is important for a well balanced wheel."

So it was flex, or stiffness(?), not tension...
shuffles ...I'll just be quiet now.
