As this is a brave new frontier, I can understand why both are not going full guns at the moment.
Their only point of reference is really Tommy Godwin, and as has been described elsewhere that historic experience is unlikely to be a true reflection of what is possible.
I flip-flop between Steve and/or Kurt not doing enough to hold off the challenge of the other. I'd imagine both is comfortable in themselves that they are putting in the right effort at this point in time. Kurt, however, seems to be the worse for wear at the moment. Both his sickness, whatever it was, and also his general appearance (he was exhibiting cracked lips the other day, and looked generally fatigued. Albeit at other times he appears bright as a button). For all I know, Steve might be the same. He seems to be keeping a lower public profile than Kurt, largely leaving his riding (and more vocal "fans") to do the talking.
