Sleep training like that is a bit extreme imo, we started with a much lower threshold (5 mins) and only expanded a little bit (+5-10 mins) until our kids started to adjust. Worked well enough for them, they were sleeping mostly uninterrupted regularly around 4-5 months. Some regressions happen but we just apply the same technique and they’re back to regular in a couple days.
