(Yeah, it's interpolating the value of 5.9 from 5.8 and 6.0. The tables do not have 5.9 in there... I see what you're saying, I guess it could be "rounding" up to 5.9, but it still has to find that data, since it doesn't exist... anyway. ;)
That was it!
I took a look in the sep file and changed the value to 0.2 and that bumped me up to 6.0%. Now, I'm assuming it won't round down, but you know what happens when you assume. Do you know where I can find the [guidelines/arguments] for the .sep files? Ie the eRoundingIncrement variable is one of many, I'd like to look into it and see what else I don't know about!
Thanks again for the help! I really didn't want to do that manually...
EDIT: I found this but it doesn't give explanations of all of the variables... If you know of anything better it'd be greatly appreciated. Thanks.
