It's a 'weight' (for lack of better term) and accepts any positive number. It determines the probability a response is chosen in relation to all available responses in the same response set. The specific numeric value is irrelevant if you only have a single response in the same response set (although I would stick with #100 for consistency reasons).
My guess is that initially the RESPONSE value was coded as actual percentage, and at some point later changed to weight but everyone kept using 100 out of habit (or to keep it pretty looking and consistent).
By using a default value of 100, you are allowing it to be extended in either direction, up or down. You can add responses with an equal probability(100), a lower probability(1-99), and a higher probability (101+).
A default value of 1 would only allow adding additional responses with an equal or higher probability, since there is no lower value you can use.
Nor do you want to, 99% of the time. You people can do whatever you want. I know I'm not stealing zeroes from the door of a loo to put them in a script so that God can look from on high and pat me on shoulder.
Why do you have to be like this with all these people who accept to help you again and again chimeric...?
They do it because they want to. This isn't charity. We work together and swap ideas. Here's a small but obvious case when people should change their habits - it's for their benefit, but nooo. Well, I know I'm going to save myself this extra bit of work.

Probability 1 per cent is the same as 100 per cent?
RESPONSE #1
-something-
RESPONSE #2
-something else-
...and the second one will happen twice as often as the first. Same as if you had written #100 and #200.
A default value of 1 would only allow adding additional responses with an equal or higher probability, since there is no lower value you can use.
