presstab, or tranz, I'm reading through the code, something I've wanted to do, but it's a bit overwhelming, huge congrats to you guys that know what it's doing.

I was trying to find some simple things, like stake age, stake interest, etc.  I found the total coins and block.
One question is why is everything * COIN, which is like 1000000?

static const int64 COIN = 1000000;
int64 nSubsidy = 1 * COIN;
static const int64 MAX_MONEY = 100000000 * COIN;//100 million

Anyway, it doesn't make much sense, one line in main.h says 5% interest, and then in main.cpp it says 100% but the exact same variable is assigned, no modifications, so wouldn't it still be 5%

I do see in main.cpp that you do some coinyear manipulations, I expect this is where you get the 40% from.
    // tekcoin: reward for coin-year is cut in half every 64x multiply of PoS difficulty
    // A reasonably continuous curve is used to avoid shock to market
    // (nRewardCoinYearLimit / nRewardCoinYear) ** 4 == bnProofOfStakeLimit / bnTarget
    //
    // Human readable form:
    //
    // nRewardCoinYear = 1 / (posdiff ^ 1/4)


I can't get macosx to compile, evidently it's an issue with maverick and some binaries.  Trying to see if I can work around it, gets toward the end, and I get unknown symbols, etc.
