I don´t think you are correct in the estimate of Chinese LCUs. In my second game I had lost a horrendous amount of LCUs in China. I was nearing 17k worth of LCU losses. And I still had about a 1/3rd of the Chinese army left (although without supply).
In this game I have suffered 12k worth of losses so far. And I now have all the Chinese LCUs on map again (no more set to respawn besides new units). As you say its hard to put a number on how much the losses are worth in VPs but its way more then 4k of that I´m absolutely certain. At least the double and I would guess its more.
I could probably make a half decent estimate by going through the saves and tracker. I agree 20-25k VPs is probably on the high side though as you say. But 15-20k is probably very close to the actual number.
EDIT: Does anyone have or know of any "quite China" kind of games. What would be really interesting to find is a game (or VP screen) of a game very there has been little to no combat in China but the initial Japanese expansion is over with (Singers/DEI/PI/Burma). That would give us a rough number on how much the Allied LCU losses outside China is worth. You can then very easily calculate a rough number on the Chinese LCU losses for a game (where there hasn´t been much allied LCU losses past the initial expansion outside CHina.)
That's basically what I've got going on in my two games. One is essentially a Quiet China, though it has picked up a little. In the other, I've lost all of China (though pretty much by choice, at least this early).
It's true that Chinese LCU VPs are going to vary a lot, but I don't take replacements in China. It just burns supply that's better spent simply feeding the LCU, IMO. Supply is already short enough as it is. It's also difficult to sort out exactly how much of the LCU VP total was Chinese, but I am guesstimating: the fall of Chungking cost me ~2K, and I had a very large stack of troops there. Almost 100 units, many hundreds of thousands of guys. I actually think my estimate of 4000 might be on the high side, as I didn't lose much other than those units that I committed to Chungking.
I'll compare destroyed Chinese LCU numbers to those I have still alive in about 30 minutes here.
