Hello Everyone!

Quick question. If we submit for the same model, variable and lead time twice within a single submission window is the second submission going to overwrite the first one? Or is the first one locked in and the second one has no effect?

Thanks in advance!

Hi Asena,

The second submission will overwrite the first submission.
