Yes it is, that's why the machine has a "Select Hands" function where you select the number of hands that you want to play.
I understand that Singer is in your head, but he had nothing to do with this. I came up with the 100-play idea myself...it's all in the archives.
The original challenge was to be ahead after one million hands. This denomination rules was an add-on well after I said I would need to play a 100-hand machine in order to complete a million hands in a reasonable amount of time, and only after Singer suggested I use his betting strategies.
And if changing denominations doesn't work anyway, then why are you sweating it?
