Check My Plotting...

Hello all, as a budding cruiser, I am currently studying coastal navitgation at home with the US Sailing book, and plan on taking a nav course this spring. I''m looking for a competent navigator to check my work, with relation to plotting;true to compass, factoring variation and deviation. Here are the #''s...
Compass Rose says... Var7deg30W, (2000), annual increase 10''.
My #''s- 10''x4=40 div by 60minutes =.66. New Var=7.66.
My bearing is 130T+ 7.66V =137.66M - 4E(dev)= 133.66 Compass.
Question: If my #''s are correct, should I steer a compass heading of 133, 134, or try to stay in between, (hard to do on a boat)? Do these small half a degree increments matter? Thank you!
