I took a second look and said those curves are more than (x) inches apart. Metric side was ok.
Reminds me about when we were installing a big GT power plant in Korea(Seoinchon). Everything was in inches, etc. The Korean foundation labor force was issued a dual tape measure - oops!! The metric side was 100% correct, the metric side - I never had seen an inch broken down into FIVE
quarters. That contractor had a lot of rework at his expense
