It needs some work but it goes like this:

Estimate X is 10000 (amount, time or whatever). It will come from A (5000) B (3000) and C (2000). A will come from A1 (500) A2 (1700) A3 (1300) A4 (1500). A1 is derived from A1.1 (200) A1.2 (200) A1.3 (100). The deeper you go in the analysis the more difficult it will be for anybody to check all the data and prove you wrong.
