why the current block = 20 in scv pool?

There has been one change in reward schedule - first 100 blocks will have 1 coin reward and not 150. Also, first 20 blocks, i.e. 20 MIN have been already mined - this is due to some problems with stratum pool mining from block 1, i.e. blocks found by the pool are orphaned if block height is less than 20 (I believe this is X11 coin issue). We've decided to go around this by solo-mining first 20 blocks. These 20 MIN will be given to the next poster in this thread after I post this.
