If you're asking me, I think anything that gives a broader view to assess the level of drop in more time would be beneficial. Charities are very different. I think the government is just looking to accurately assess that level of magnitude, but if someone has good months or bad months but overall they are going to take the hit, it would be ideal if that could be factored in. I think if something like that could be considered, it would make sense.
