Good to keep a sense of humor about it! Of course, it doesn't work based on owner demands, and few if any, business decisions are premised on the differential in confidence level from 95% to 99%. I re-ran the significance tool using n=500 for your observation with the resulting margin of error/confidence interval. Bottom line, CR sample is robust, but doesn't address loving the car anyway due to high TGR.
