It doesn’t feel like a core part of the pledge to me.
I mean, reporting isn’t (and hasn’t been) part of the pledge while giving is, so that makes sense!
I recognise that I can use part of my income to do a significant amount of good. Since I can live well enough on a smaller income, I pledge that from __ until __ I shall give __ to whichever organisations can most effectively use it to improve the lives of others, now and in the years to come. I make this pledge freely, openly, and sincerely.
