Richard Hills asks:

What about "penny wise, pound foolish"?  Cross imps limits
one "luck problem" of a single random imp landing NS or EW
at the cost of a huge "luck problem" of double-digit imps
due to the luck of sitting NS or EW when a ridiculous
result happens at another table.

Suppose the NS scores on one board in a seven-table Howell
imp pairs are:

+630
+630
+630
+630
+630
+630
-1700 (ridiculous result caused by South insisting on an
esoteric convention and North having a memory lapse)

At olympic-scored Butler-with-a-datum (top and bottom
scores excluded before striking the datum), the EW players
at the six normal tables get their fair result of a flat
board.

But with cross imps, the EW players at the six normal
tables lose a zillion imps, and their matches, merely due
to the random luck of the EW direction in which they sat.

Aussie national champion and mathematician, Warren Lazer,
has devised an olympic-scored cross imps method which
fixes this problem.  For each pair, their imps are crossed
only against the middle four of the other six scores.
