### 2/5 — ECD calc error

*2023-09-13*

Thought I’d try the app to do some quick ECD checks. Was super impressed by the interface and the ease of populating the inputs. The slide bars for changing Depths, ODs etc up and down are great but the calculated ECDs are two ppg less than my MW so I have lost faith in the outputs.
