Into the Nentir Vale (was BECMI/4e Conversion)

Yesterday's post on my BECMI/4e conversions really took off and it seems there is a ton of interest in it.  So I am going to explore the idea further.
Now I have been conversions since, well since forever really. Converting fluff, converting plots. That is easy. Can do it on the fly.  Converting the monsters is also no great task, but it does require some care.  Since I am already doing the work of 4e to BECMI I might as well through 5e into this too.
Why not.

When I convert say between 5e and TSR D&D (1st, 2nd, Basic) I just swap out the monsters. It works nice.  When I add 3e into the mix then I want to look over the monster for any feats or powers it might have and make sure those get preserved somehow.  4e is a bit trickier.

4e, more so than either 3e or 5e, has a strict XP budget. You are expected to level up at certain points in the game.  This might not be true of EVERY 4e game, but it is of HPE adventures.
The other factor working against me is the 30 levels of advancement in 4e vs. the 20 in 1st, 2nd, and 3rd.  BECMI helps me out here with a nice range of 36 levels.
I want characters to progress through these adventures AND still stay within their target levels.

So I am building a spreadsheet (I am a numbers guy afterall) to help me calculate the XPs given per adventure.  This will help me find the appropriate monster replacement for each game, help me balance the XP so the levels come out right and give me the exercise of going through each adventure and understanding each encounter.

I am opening up my spreadsheet so everyone can have a look and comment.  I am not opening it up to contributors yet since I also want the exercise of going through every monster in every adventure.
I added the data from yesterday's conversion and added a 5e column as well.  The 5e data has the advantage of using a VLOOKUP to allow me just to put in a CR and it spits out the XP.  I could do this with the 4e and BECMI ones as well, just have not done it yet.  I could also easily add Swords & Wizardry to the mix if people are interested.

If you scroll to the right (Col "O" to "R") you will see I have summed up the XP per adventure and then figured out how much per character based on the default (4e) party of 5 or a party of 6.  My feeling is that to make the levels work out with 5e I am going to have to assume that 6 characters are going through.  This should also make the combats faster.  I have not figured out what the optimal number of characters is for BECMI yet.

I will also have to convert the treasure.  There are some wildly different assumptions on what treasure needs to be in different versions of the game.  You get lots in 4e, not a lot in 5e, and in BECMI (or at least Basic) Treasure also gives you XP.

THEN I need to figure out what this all means for my Come Endless Darkness game.  If I run this set of adventures the party goes up against Orcus. In CED I also wanted them to fight Orcus.  Have to figure it out later I guess.
