These lines show stage-over-stage percent growth (each stage vs. the one right before it), not cumulative growth from Stage 1. Both revenue and complexity jump hardest going into Stage 2, then the growth rate tapers in Stages 3 and 4 — even though the totals themselves keep climbing.

Stage-over-stage growth, not cumulative. Revenue: Stage 1 is the baseline (0%); Stage 2 is +100% (the business roughly doubles); Stage 3 is +50%; Stage 4 is +33.3%. Complexity: Stage 1 is the baseline (0%); Stage 2 jumps +360% (10 → 36); Stage 3 is +220% (36 → 78); Stage 4 is +170% (78 → 136). Both curves peak going into Stage 2 and taper from there — the growth rate slows even as the totals keep rising.
