Example (LESSON_UID = "basic-139")

# Basic drill L139 topic-13 micro-8 pattern-10
LESSON_UID = "basic-139"
spin_a, spin_b, spin_c = 16, 928, 446

def gate(v):
    if v < spin_a + 8:
        return "low", v ** 2
    if v > spin_b + 139:
        return "high", v // max(1, 8 + 1)
    return "mid", v + spin_c

cand = [24, 42, 187]
for candidate in cand:
    lbl, val = gate(candidate)
    print(candidate, lbl, val)
