Basal Rate Calculation

I never agreed with the estimated basal rate calculations. The Panceum calculator for iPhone seems to be more accurate. The equations are as follows:
Total Daily Dose (TDD) = Body Weight (pounds) / 4
Total Basal = TDD x 0.4 (40% sometimes 50%)
Hourly Basal = Total Basal / 24

My calculated basal is 0.66/hr
The Pancreum Calculator says 0.43/hr
My actual is 0.4/hr

What is your?

Your calculations suggest I should be at 1.25 a hour. I am 3 weeks into pump using and I need 2 a hour for most of a 24 hour period. 3 am to 6am I am at 2.25. Your suggestion isn't right for everyone

Is there are different calculator for people on MDI vs people using an insulin pump? I ask because TDD on a pump is usually lower than when on MDI. My TDD on MDI was 21 units and my average TDD on my pump is 17.5 units. Both these numbers are significantly lower than the calculator you provided which indicates that my TDD should be 30 units per day (I weigh 120 lbs). Individual insulin sensitivity is also a factor and may explain, in part, why I have a lower TDD. When I started pumping in 2011, my insulin sensitivity was 120; it has since been adjusted to 100. My AVERAGE daily basal insulin is .49 units/hour but that varies by time of day with a high of .625 unit/hr from 3 am to 7 am to counteract Dawn phenomenon to a low of .125 unit/hr from midnight to 3 am. I'm also aberrant in that my % of basal insulin to total insulin is 68% and it is usually expected to be around 50%…just more data supporting how individual a disease diabetes is and no "one-size fits all" applies.
