What the score does NOT say. A high Buffett-Fit score is a pattern-match against documented criteria, not a forecast. A stock scoring 90 today can underperform if its underlying business deteriorates faster than the score updates. A stock scoring 30 can outperform if the business recovers. The score weighs current fundamentals against a documented framework: that's all it claims to do.
How invest-like measures this
