Some of the points will be based on the random attacks, so a straight halving would not be "fair".
However I have always seen Mammoths as written more for fun than balance, so unless you are planning on using it in the sort of game where you aim to stomp your opponent halving everything for a few games to see if it seems grossly under/over costed would be a quick way to get the model on the table.
