American IPA ingredients

I don’t know what I don’t know so… If I may ask maybe one final question.

In my recipe I am using 42# of grain and 39.29oz of hops.

I’ve never seen an input ratio for hops to grain, oz’s to pounds. Is there such a thing? If so, am I out of wack with my hop additions?

Bittering hops 1.13oz Mosaic 12.25% AA @60mins
                    1.81oz Centennial 10%AA @20
                    1.81oz Citra 12%AA @20
                    1.81oz Mosaic 12.25%AA @20

.91oz ea. of same combo @10 mins

2oz ea of same combo @ 194*

4oz ea of same combo dry hop 3 days
                    4oz ea of same combo dry hop 4 days

I hope that was easy to understand!!

Thanks again!!
