No, I just went in and did the lifts and moved on, sticking to Korte's ESM principle. As I saw it they were there to keep me ticking over between max efforts. Don't forget also that you're deloading.
I think if you were to try and drag out an intensity phase more than 5 or six weeks then you'd probably have to slide over to a WSB-style workout as conditioning slips away. For the four weeks of Korte it shouldn't be an issue and every single day you have a big lift to make, anyway, so you don't really want to spend your energy on the 60% lifts. That's just my opinion, though.
