Hell, we're only 3-2-3 this season when leading after 2 periods. We're 28-12-7 leading after 2 since Albie got here, and that includes 6-0-1 last season. That means we're only winning 60% of the time when we have the lead with 20 minutes to go. How about BC? 42-10-2 when leading after 2 the last 4 years. (EDIT to add: PC, the team used in the blown leads example? 42-9-5 in the last 4 years when leading after 2.)
May I ask where you got these records? I had started to compile the game data from the 2020-21 and 2021-22 seasons and after you posted this I worked on all the BU, BC and PC games. Unfortunately, I have different numbers for all three teams so I'm concerned I have made numerous mistakes entering the data. Here are the records I have:

If my data is correct then BU hasn't had the lead as often as BC and PC and they haven't done as well as those 2 teams, but their record is not nearly as bad as your posted.
