That's a fallacy of probability. There's no proof that one race being closer means another one will follow the same pattern. They are each individual races. That +10 district could jump to +20 or +2 or whatever other number at, at least in theory, the same amount of probability.
What you're doing is just making yourself feel better. Does it show progress? Absolutely, and that should be commended. But let's not act like it's a victory for anyone but republicans.
You should probably shy away from using terms you don't understand. If seats in South Carolina, Kentucky, Georgia, and Montana are all more competitive due to a rise in Dem voting, that's plenty to extrapolate a national trend out of. Nate Silver has been doing just that recently.
