Well, I played a Grail Foundry that didn't really work, a Bootcamp Foundry that didn't really work, and a Director Haas Foundry that didn't really work.
Me and anybody else brewing with rough lists are probably responsible for most of those losses.
It's unquestionably worse than HB:ETF just giving you free money constantly with no downsides. Every ICE you tutor makes R&D weaker, makes Beta Tests weaker, gives up information, and due to Parasite spam it's hard to accumulate enough of your NEXT to do anything.
If you are running Bootcamp then you're committing money to ICE without the Runner even having to make runs and potentially be surprised. If you're not running Bootcamp then the Runner controls when your ability fires, which means you won't get it when you need it most.
That said I don't think it's as bad as these stats say because the stronger players self-select into HB:ETF lists that are also more tuned. The ID is probably capable of being only 5% worse than ETF.
