Charting data accurately is really really hard. On one team we had a guy who said charts are for asking questions, not making decisions, and I’ve found that to be a pretty safe default.
What they needed was hourly updates, which they had from the other service they subscribed to, which was ignored by the captain. Despite the staff being fully aware.
And the captain and staff should always be reading weather data from two sources anyway, for redundancy and accuracy.
These guys had plenty of information but over-relied on one which was 6-12hrs out-of-date at the worst time, which no indication it was old data.
These are solvable problems that have little to do with tiered pricing or a cheapness on part of the company. Both by the above redundancy and the weather company dating their data, and fixing software bugs for such critical software.
