That sucks it does matter I can't do a background without the starting level it affects the background.
Crawling back to something resembling coherence now, so, just to say, look at it like this. Can you give me a character background that's more than two paragraphs and has a decent amount of hooks in it for me to play with? Here, have at least a level. You are at that point at minimum a 9th level gestalt character. So you can at least write like you are of some heft character wise. Give me something like some notes on developments you're hoping to see for your character as the game goes on and stuff you otherwise want to work towards? Helps you and me, and thus helps you tangible styles.
But by contrast, lives are busy, people can tire. It's not terrible to only put so much in, it just means being not as developed.
On a similar note, I'm more trying to encourage you to create conceptually (and thus textually), towards shooting for the level range you more picture for yourself. Give me an involved concept and thought out organization I can help you carry through to fully fleshing out as needs be? That will move towards the upper end of the scale.
Another way to look at it is like this. I notice a bit on Ell that submissions for characters can be a bit boom, plunk down submission, drop the mic, done. And that's still possible, but I would otherwise be perfectly fine to handle them here in a more dynamic way, which is to say, to ask as I get something "can you give some more detail to this" or "would you like to go in this direction". So for instance, something like "I was hoping to be higher level than my character currently is, is there something I can do that would take me there", is a valid question to ask.
