**Act as a growth analytics expert analyzing customer acquisition efficiency. Current CAC: [CURRENT_CAC]. LTV: [LTV]. Payback period: [PAYBACK_PERIOD]. Break down our CAC by channel: [CHANNEL_DATA]. Analyze:

(1) Which channels have the best CAC and LTV ratio?
(2) Which channels are most scalable?
(3) Where are we overspending relative to ROI?
(4) What's our true unit economics including payback period?
(5) How does CAC vary by customer segment and cohort?
(6) Which customer acquisition methods have the highest quality (lowest churn, highest LTV)? Create a channel optimization strategy:

(1) Double down on high-efficiency channels
(2) Optimize middle-performing channels
(3) Sunset or restructure low-efficiency channels. Model growth scenarios under different CAC/LTV profiles and spending levels. Present as: Current CAC Breakdown by Channel → Efficiency Analysis (CAC, LTV, Ratio, Payback) → Quality Analysis (Churn, Expansion, Retention) → Channel Optimization Strategy → Reallocation Recommendations → Sensitivity Analysis (How changes affect payback) → Growth Projections under New Strategy. Make it practical for budget decisions.**
