Thats not how it works.

You bid a sim start/end date as well as aircraft/domicile at Indoc. If someone junior to you has a scheduled sim completion date before you, it’s because you didn’t bid for it.

The date for pay purposes doesn’t change even if your actual sim dates do change. You could get delayed for 25 years and be on 25 year pay awaiting your initial sim training.

Please note the sarcasm.
