Ikaruga

Hi, i'm playing Ikaruga for Xbox Live Arcade and i'm trying to get the achievements for A rank in the different chapters. Can somebody post the scores for A rank? The FAQs listed here only show S rank scores or above.

So let me start with Chapter 1. Here you need 2,000,000. By the way, I can also confirm that you get B++ rank for 1,999,930........ :-)

I noticed that the requirements changed with difficulty level. The A rank with 2,000,000 in Chapter 1 was obtained playing on easy.
I've just beaten the final chapter on easy with 4,000,000 and got A. Again, I was close by scoring 3,999,000 and something, but just got B++ XD
