I'm pretty happy about being in the top 10% (although the two one-star ratings I got do still sting a little).
Jam comments can be a little weird, and it's not uncommon for them to mismatch the final scores. There's a lot more at play than just 'do they like the game?' Since people are churning through a ton of games they may only bring up one or two aspects that they really liked without mentioning anything else to save time, or they might be worried that an overly critical comment may invite retaliation (which is dumb, but still a possibility), or they may not feel the need to say anything at all (my game for instance had way more ratings than comments, and I doubt the one-stars were given by people who commented).
IMO sometimes the important thing is to look at what people aren't saying. Again taking my game as an example, almost everyone who commented had something nice to say about the visuals and the concept creativity, so I knew I would score well in those areas. But comments about the audio were very sparse and it ended up being my lowest scoring category.
