+    <p>ProfitCtl compares two illustrative saved scenarios. The steady-state example shows $2,000 in revenue, a 95% operating margin, and a cost per user of $2.00. The pilot example shows $6,500 in revenue, a 69% operating margin, and a cost per user of $12.40.</p>
+    <p>Recurring revenue is $2,000 in both. The pilot has $4,500 more revenue, a 26-percentage-point lower operating margin, and $10.40 more cost per user. ProfitCtl identifies the leaders for each measure so you can compare the full trade-off using your own costs and assumptions.</p>
