Swinging Sunlight#209

DNA/A Grade is DNA Analytics' overall grade for the core. It blends three tiles: Ratings (the game's official PWR and ADJ), Racing (how often it wins and places compared with what's expected for the field sizes it raced, plus how often it beats the pre-race sims; 1-gate races don't count) and Offspring (its officially rated offspring, after allowing for each mate; counts from 3 rated offspring, up to 60% of the grade). The grade always sits between its tiles.

Bloodline (parents count most, grandparents a little) only counts while a core has little racing of its own. Genesis cores have no parents, so bloodline never counts against them.

Grades are rankings among rated cores: S is the top 3% (S+ top 1%), A the next 12%, B the next 15%, C the middle 40% and D the bottom 30%, each split into +, plain and -. The trait rows compare its own stats with its offspring; the % is each trait's weight.
