Keeping it under 4k RPM's is only a recommendation. I varied my RPM's, speed and amount of acceleration etc during my break in period and the dealership said I did very well with the break in. It is nearly impossible to keep it under 4k as anytime I went over 40 it was already over 4k. You should be fine... and Welcome to the forum!
