So occasionally I see comments on other forums that Coach Jack is too easy or email feedback. It has always been possible to make hard plans but it was not so obvious. We are making it obvious and added a few more plans that fit the crowd that wants to really work hard.
We also added some sequences (tempo blocks for example) and improved a few of the other sequences. We have some other changes coming to coach jack soon. Nothing major but just more stuff to make it easier and simpler and more optimizations to some of the sequences.
