Yes, all of the early kilts I have seen which have been made from Black Watch, or a Black Watch variant and pleated to stripe, have used the half repeat, as John describes. This includes the earliest documented tailored kilt, a Gordon regimental kilt c. 1796 (box pleated, from 3 yards, 2" of cloth), a Seaforth kilt (MacKenzie tartan) from the same time period, also box pleated, from 3 yards, 2" of cloth, on up to kilts in the latter part of the nineteenth century.

This is the standard way in which Black Watch based tartans are pleated to the stripe.

(A lot of these early kilts are documented in All About Your Kilt by Bob Martin).
