In pumping insulin (and most people use a little less on a pump), John Walsh suggests for a person of 73kg a starting TDD for T2 would be about 7-18U, starting TDD for T1, 22-29 (both in the side of safety) then all averages physically fit; 33u, moderately active;40u, sedentary or adolescent 50u. There are higher doses for those in the second two/thirds of pregnancy and for severe stress and if people have DKA, infections or are taking steroids he says it could be between 80 and 140u.
(and then insulin resistance and how much of your own insulin is still being produced plays a big part)
So huge variation.
