ideally, we'd like to see 3 columns of K, BB, and K/BB, but if only one column is allowed for one category, I guess the much more informative format 60/40 is preferred over just the ratio number 1.5. we can do the math ourselves.
The first thing is that I know they only have a column per scoring category the only exceptions being IP and H/AB so they will not split out the individual numbers that go into a ration UNLESS those individual stats are also a scoring category. i.e. if you also are scoring Ks and BBs for your pitchers then you will see a column for each.
The second thing is that there is no logic to your request. The scoring category IS a ratio, it is not an absolute, just like k/9 or ERA so 99.9% of users want the ratio, not have to go and calculate it manually
