Question about calculating GPA in major

[snickus]

Hello, in undegrad I double majored in Philosophy and English. Both programs required 10 courses. I took 10 upper-level Philosophy classes, so calculating my GPA there is straightforward. However, I took 11 upper-level English classes. For the first 10 I took, my grades were 7 As and 3 A-'s. In the 11th class, I got a B. I took that last one during my final semester after I'd already completed all of my major's requirements. Since I didn't need that 11th course to meet major requirements but basically took it as a general elective, do you think I could exclude it when calculating my GPA in that major? Or is that abominably sleazy and it's expected that I count it in my GPA? I'd of course like to use the higher GPA  but what I'm really trying to learn is what's the proper way of calculating in-major GPA: Count just the courses that filled my major's program of study, or every upper-level English course I took? I'm thinking the latter, since adcoms won't know what my program of study required, so have no reason to think that last course wasn't part of my program.
