Funny...I worked for a professional engineering company for nearly 20 years. Each project manager (new to the company) was allowed to use a starting project number of 3000 so if they got 18 new projects, their most recent award would appear as 30018. Clients could easily assume they have a very senior project manager with lots & lots of closed projects behind them.
Gave the impression a project manager was very busy with securing project commissions.
Smoke & mirrors, for sure.
