Well, at least we agree that Choo is a better value in stadiums other than Petco. As to Petco, the one versus three range rating is a debatable one. Yes, in Petco, the differnce could override Choo's greater obp and greater slugging versus righties (even with the park factor), even though performance v. righties is a more significant factor than performance v. lefties; since there are substantially more righty starters than lefty ones, that is a given. However, even Petco teams have to play on the road, and while Choo provides speed, superior offense, and a great arm at Petco, he provides the offensive production in regular and power parks that Ichiro's production cannot nearly approach.
Also, I'm curious to why you discount reading the columns for interpreting possible production: they (along with other data on the card) are the only information we have for doing so. Yes, the numbers on the card on equal: a home run on a 7 in a column denotes six times the possibiliy of a home run on a 10 or a 12. However, taking that into account, you use the columns and their various and varying "number hits" to interpret the possibilities of both positive and negative results. We then use other information on the cards--such as running numbers or N or W power ratings--to amend those results.
We may, as you have done, formulate ratios and formulas from these columns to expand upon these results, but you can NEVER do so without deriving information from these columns. Also, these ratios and formulas do not justify themselves. You must explain how you derived these formulas from the given information on the cards, and you must explain why these formulas or ratios actually support your various statements and arguments....which you never did when asserting your xbh/h ratio as a way of determining the value of one card over another.
Anyway, good luck on your season...I will be nothing but pleased if your team proves my evaluation and prediction wrong.
