At the moment, I'm not that good. But always improving!
Comments welcome.
This post will be an index of my scores, updated as necessary. I plan to comment if/when significant progress has been made, but not more than once a week.
Dodonpachi DaiOuJou (X360)A-Laser: 77,600,000ish, 1418 Chain, died stage 3 midboss after a bunch of unexpected deaths to the stage 2 boss. 7/26/2012
Milestone: 5/31/2012: Near-perfect run of stage 1-1. 803 Chain, 24 out of an ideal 28-29 million. Lost the chain right at the end; the transition between the last two bees. Regardless, it felt really good.
Nailed the first stage pattern. Working on finessing the stage and boss patterns for score; currently I can get 27-28 million consistently. I'm also working on finalizing my boss milking. I've also begun to fine-tune my stage 2 pattern, and have managed several near-perfect runs. In the process of developing a stage 3 pattern. 7/26/2012Goal: 1CC first loop at least. Ideally 2-ALL.Dodonpachi Dai Fukkatsu (X360)A-Strong: 4.4 billion. Wow this is terrible.

Have 1CC'ed the first loop as Type-A and Type-B.
Dodonpachi Dai Fukkatsu Black Label (X360)Haven't played yet.
Ketsui (X360)Best is about 31,000,000. I'm really loving this game, and can see myself spending a lot of time on it.
Mushihimesama (HD, X360)Haven't had a decent enough score to bother posting, but have almost 1CC'ed both Original and Original 1.5 MAX.
Mushihimesama Futari (X360)Best with Normal Reco is about 90mil, which is really bad for me.
Normal Palm - Original - 158mil, stage 5.
Total fluke run-- I don't like normal Palm at
all, but somehow this is my current best run. Go figure.
Mushihimesama Futari (iOS)Original/Hell: Normal Reco: 222,023,739
