Ann: FY17 Full Year Results Commentary, page-19

you are right regarding they don't have control over GP%. in fact in the conf call, Domonic commented on the CSP margin could improve this FY as the incentives are heavy, but overall based on experience, he conservatively concluded that despite the incentives he does not expect the gp% to move much.

They do have some lever on this front by selling more higher margin services to the smaller customers outside top 10.

I do find it necessary to keep track of this line as you don't want to see it decline, and much of whatever little % improvement they achieve falls through significantly as pointed out about the fixed cost base.
