OT: Assessing causes

When (if) people assess the cause of their performance, what does it say about their play?

For an example:

When I win (cash): A/B
20/30% - Made few mistakes, just solid poker
40/20% - got several key lucky suckouts
30/50% - just held on longer while everyone else blew up
10/ 0% - other?

When I lose:
50/80% - Got sucked out on
30/10% - Never got the lucky card I needed when behind
20/10% - blew up
0/ 0% - other?

So, in their own words, is "B" tighter than "A" or a more solid player or don't know don't care?

The reason I ask is I reviewd my notes from a group of SnGs, and saw (for example) a higher number of "played stupid draw and lost" type things than I would have thought, and wondered if these types of observations might be a good indicator of where my game needs work (duh), and thought about what sort of distributions above would look like for a solid player. (or this is just a pointless philosophical musing..).
