Interview Prompt
Every model version, a unique pairing of mdl_name and version, goes through a series of training runs, and we want to know how often a version stumbles right out of the gate. Across all versions, take each one's very first training run by train_at and return the single percentage of those first runs that ended in a failed status.
Summary
Some model versions never recover from a bad opening run.
