Yup. Kinda like what I was gonna suggest. just tell it you have a lot more ASIC's to use in order to build a cache.

But each WU really doesn't add a lot of hours, so it's still gonna be pretty hard to get to your goal. I know it'll be impossible to make it to mine, but I'm starting to see that I should never expect to get to that level on any of the campaigns as long as Henri keeps cutting them so short.

EDIT: And, oh, you could probably even use a combination of an inflated ASIC count in the cc_config.xml and an app_config.xml project_max_concurrent count of your real number of ASICs to keep that cache as bloated as possible, for as long as possible, while still only crunching the correct number of WU's at a time.
