Nah, with no initial gravity to work from, just aerate for the first 3 days - the O2 is only needed for yeast development, then on the fourth just give it a bit of a stir to help lift out some of the dissolved CO2 and then add about 1/4 of the amount of nutrients that you gave it and stir it in.
Then airlock it off and if possible just give the fermenter a bit of a swirl just resuspend any yeast that may have dropped out.
That way you've loosely approximated aeration to 1/3 and SNA without any numbers (taking a start gravity gives you greater control of the ferment, and allows greater accuracy in managing the ferment).
