Weizenbock 1.5# Munich LME replaced by 2# Munich malt
Robust Porter 1# to 1.5#
Dunkelweizen 2.2# to 3#
Dubbel 0.8# to 1#
Rauchbier 1.3# to 1.75#
Scottish/70 0.25# to 0.5#

I guess I'll not worry about setting a ration and just read the rest of the recipe, good thing too! As long as partial mashing just one of the ingredients this way doesn't throw off the balance of the recipe I'll be all set (no that I'll know, so why worry, relax and have a homebrew!!)
yeah, the Allgrain and Extract versions of recipes in BCS aren't going to have a direct translation for every ingredient on it's own, it's an equivalent for the whole recipe. The conversions have been done for you, and they're written so the all-grain and extract will be as similar as possible. For example, the recipes for the Munich Dunkel and the Robust Porter won't substitute Munich LME for Munich malt at the same ratio because each of those recipes has all sorts of other things going on.
If you find some All grain recipe that you want to convert to extract on your own:
Munich Malt contributes 1.037 potential gravity points, you have to multiply that times your mash efficiency, for a mini-mash w a grain bag, say 60% efficiency?? (it will be low) or 1.022 points (37*.6). So each pound of Munich Malt at 60% efficiency will get you 22 points.
Munich LME
http://www.weyermannmalt.com/eng/produkte.asp?idkat=27&umenue=yes&idmenue=37&sprache=2 from Weyermann's gives 1.035 - 1.040, split the difference and call it 37 points per pound in the Munich LME
So if a recipe you are trying to convert calls for 1 pound of Munich LME , you'd need 1.7 pounds of Munich malt in a mini-mash (22*1.7=37) if your mini-mash is 60% efficient. If your mash was 70% efficient, then you'd only need 1.5 pounds of Munich malt to make up for 1 pound of Munich LME.
