Rorqual bonuses - rorqual bonus in deployed mode worth fuel cost?

Heavy water -

My rorq pilot boosting 2-3 hulks depending on the day, will be able to do the 10 min deployments soon. Lind of annoying to have to deploy him every 10 mins but my question is. I have warfare link 5, foreman 5 director 5, leader 5 etc, with foreman implant and the 3 links running on top slots. How much more efficiency does the deployed mode really give, and is it worth the cost of the fuel which i think is cheap though may be annoying to keep stocked in the rorqual if i mine a lot?
