Mechanical valvers, what's your INR vs. Warfarin dose?

[MartinF]

60 years old, active walking/running
target INR = 2-3
have tissue valve
take 81 mg aspirin
warfarin: 3 mg 3x/week, 4.5 mg 4x/week for 27 mg/week total
INR has been in target most of the time in past 4 years, it's been 1.9 a couple times recently. I get tested every 6 weeks when in range. Test is done day after my 3 mg dose so it's probably my lowest point.

Carbomedics carboseal mechanical valve with valsalva graft.
Target INR 2.5

My inr tends to float between 2.4 and 2.8, but always in range thanks to self testing!!!
Not a consistent diet either!
