[Albion] How often a single early goal nullified late?

Not just a rhetorical question. How often will an early solitary goal get equalised in the last few moments? Seems to happen all the time to me. So much so that I was fairly confident it would, even more so with our good record of scoring late this season. Easy to be wise etc, you will say. But anyone done stats on it? So pleased for NM though. What a stunner!
