Instead of testing all possible combinations (which would require dozens of samples), we designed a two-round progressive protocol: Round 1 tested 4 base configurations to identify the best-performing architecture, Round 2 tested 2 optimized variants of the winner. Six total configurations, two days of testing, one clear direction.
Two-Round Progressive Testing
6 formulations, 2 days, 2 rounds — maximum decision info from minimum samples.
Key Result
6
configurations tested across two progressive rounds

Engineering Story
Why Only CORIO
Smart experimental design is about extracting the maximum decision value from the minimum number of tests — because in product development, time is the scarcest resource.
