Should I withdraw?

I sent a story to a semi pro fledgling market over two months ago. There was little information about it on Duotrope at the time. Now the responses have started to be reported and I see there is a pretty high acceptance rate. Over fifty percent. That's high and to my mind implies standards are dodgy. Maybe I'm wrong there.

Anyway, I'm wondering, even if I am accepted there, (I could be one of the unlucky one in two) is there any point in being accepted, seeing as how the acceptance rate is so high? I don't know whether my heart would sink or rise if I saw an acceptance coming in from there now.

Also, I've checked the site periodically and it hasn't done anything in all that time. I'm wondering what they are doing with all those stories they're accepting.

So, basically, I'm wondering should I withdraw and start sending it out to some more respected markets. It has already got three, pro/semi pro rejections and is a difficult genre fit to define.

What would you do? To withdraw or not to withdraw, that is the question. It says not to query before 120 days also, so I can't even do that.

Also, if you think I should withdraw, how should I word that? Any ideas.

Hmm, I think you've persuaded me to hold my fire. So impatient though. Thanks you both.
