How do these numbers look?

I'm cutting cars for a church workshop. I'm using the stock axle slots and pennies for weights. I've never built a car with stock rear slot location and have a question. I get 25 pennies (2.30 oz) behind the rear slot in our wedge cars. This gives me a COM of .9251 which seems safe to me. Do I need a higher COM using stock slot location as opposed to a rear axle that's further back? I've searched this topic and found that most recommend 1.5 oz behind stock slot and the highest I saw was 2.0 oz recommended.

That seems like it should be safe. Can you send a picture of the car?
