My tension these days comes closer to matching what a label or pattern will say it should be with whatever size needles. Because I have a hard time holding the yarn consistently with my right hand my English style is less consistent and more inclined to look sloppy. If I concentrate, it's not bad. Wait a minute! I just remembered: To practice holding the yarn in my right hand I was knitting one sock English the other Continental and as long as I really paid attention I saw no appreciable difference between the two. My sometimers is high gear today. Really it's the purling that messes me up, English style that is.
If you ever have the chance to try the wood needles WEBS and Knit Picks sell, you might like them for socks. More grippy than nickel plate and less than bamboo.
I should never overestimate my basic arithmetic skills.
