KTBR的缺点是它只看到过去，而不是将来，因而它是用于拓展业务的残留部分。
The downside is that the KTBR is backward looking, and it’s only the leftover portion that can be applied to grow the business.
我不准备拓展这一部分，毕竟这节课不是概率论，但我希望你们能记住这个公式，并且学会应用。
I'm not going to expand on this because I can't get into — this is not a course in probability theory but I'm hopeful that you can see the formula and you can apply it.
尽管“拓展”部分很重要，“保护”部分也是必不可少的。
While the 'extending' part is important, the 'protecting' is essential.
