Can someone tell me why, when I start playing Tempest with multiple credits "ticked" in, that I get scores of around 90K at level 15 (having started on the hardest level available after power down), but when I start playing Tempest with a SINGLE credit "ticked" in, about 8/10 times I get scores in the realm of $150-$200K by level 15 (again, having started on the SAME level as the score for $90Kish)?!?
Is there some score doubling bonus I am hitting but not noticing???
Which score is more accurate to what it should be at level 15? $150K-$200K or $80K-90K?
