I’m not sure what the answer is but what I can tell you is that I once asked a shaila regarding something similar but different. If I have $100 is it better to give it all to one poor person because then you are helping him significantly or split it up and give $5 here and $10 there…even though they are less significant donations? I was advised to split it up because with if you give $100 to one poor person you get one mitzvah and if you give $1 to $100 poor people you get 100 mitzvos. Its possible that the $100 to one person will be big but not as big as racking up lots of mitzvos of Tzedakah. So if you are not wealthy and want to make the most of your Tzeddaka money spread it around as much as you can.
