Received Lease Offers from Continental in Section 3-3S-3W. Need advice

I’ve been given three options for a small (0.63 nma) lease.

3 year lease term, with a 2 year option, or a straight 3 year lease.

Option 1- $752/acre bonus with 1/8 royalty (12.5%)

Option 2- $502/acre bonus with 3/16 royalty (18.75%)

Option 3- $402/acre bonus with 1/5 royalty (20.00%)

I’m considering a counteroffer of $800/NMA and 20% royalty. Is this reasonable?

Thanks!
