Absolutely right. What I meant was, when you take a cross at F3 and cross it again, you are starting over again at year 1 of 7.
If you're lucky enough to have all the traits you needed in two parents of a primary cross, then you can select the tomato you want in just seven years, which is great!
If you need to do a side cross along the way, to combine traits from another parent or parents, it is a longer process overall.
