I’ve been dealing with lawyers and court recently, they may be above average in terms of intelligence and drive but most wouldn’t be extremely above that average. I’ve had to explain fairly basic math, with easy numbers (fractions like 1/2 and 1/3 regarding pay structure), several times already. Ie
base = 100
bonus = 1/2 * base
total = base + bonus.
Still had to explain that bonus is 1/3 total not 1/2 total.
