WHIP and K/BB-ratio

Today I compared the stats of a game I scored with the official stats (I score the MLB games I watch on TV as a hobby). I noticed a difference in a pitcher's WHIP and K/BB-ratio. It seems that IBB is not included in the calculation of WHIP and the K/BB-ratio in iScore. Am I right? I've watched baseball games on TV since this season, so there's still a lot to learn for me regarding scoring, stats and so on.

Today I noticed that there is something strange happening with the calculation of the batting average against.

Team A batting stats:
PA: 49
AB: 42
H: 15
BB: 6
HBP: 0
SAC: 1
AVG: 0.357 (= 15/42)

Team B pitching stats:
H: 15
BB: 5
IBB: 1
HB: 0
BAA: 0.349 (= 15/43)

According to the pitching stats, there was one AB more than according to the batting stats. Based on these numbers, I'd say that either the IBB or the SAC is included as an AB in the calculation of the BAA.

I've looked at the numbers of some recent games I scored. I believe the IBB's are included in the calculation of the BAA as AB's. The numbers of another game:

Team A batting stats
PA: 50
AB: 41
H: 17
BB: 8
HBP: 0
SAC: 1
AVG: 0.415 (= 17/41)

Team B pitching stats:
H: 17
BB: 6
IBB: 2
HB: 0
BAA: 0.395 (= 17/43)

According to the pitching stats, there were two AB's more than according to the batting stats. Based on these numbers, the only explanation can be that the IBB's are included as AB's in the calculation of the BAA.

We do not include Intentional Walks in the K/BB ratio --- this seems it would be correct as an intentional walk should not really be held against a pitcher in this scenario. That ratio is showing performance of a pitcher, and an intentional walk is a decision made by the team, not bad pitching by the pitcher.

The same would be true with WHIP --- you would not want to "ding" the pitcher for intentional walks as that is a team decision, not performance of the pitcher.

For BAA, we do see that we are not reducing the number of at bats by the intentional walks, and have made the adjustment to reduce the At Bats for that calculation by the number of Intentional walks. This update will be included in the next release.

Thanks for the explanation!
