不知道这样是不是符合逻辑？

`Over time, the costs of processing go down because as organizations learn how to do things better, they become more efficient. In color film processing, for example, the cost of a 3-by-5-inch print fell from 50 cents for five-day service in 1970 to 20 cents for one-day service in 1984. The same principle applies to the processing of food. And since Olympic Foods will soon celebrate its twenty-fifth birthday, we can expect that our long experience will enable us to minimize costs and thus maximize profits.~

反驳：1 是技术使cf盈利，不是时间的原因

2 cf与of不是一种行业，即使时间对cf有效，但不对of有效

3 25年不代表of 会有经验

不知道这样说会不会相互矛盾呀！！

请大家发表一下高见~~~
