Another Graph I'm NOT Going To Share With You - Batch Window Reduction Expectations

In WLM Velocity - "Rhetorical Devices Are Us" I mentioned a graph I wasn't going to publish - essentially to protect a customer. In this post I'm again going to describe a graph I have (at least in my head) without publishing it. (And for essentially the same reasons.) I hope you find it useful, however:
I've been acquainted with a lot of customer Batch Window Reduction projects, especially in the past two years. When I hear of a new one I "plot" the situation on the "graph in my head". So, if I tell you that what you're trying to do is likely to succeed (or conversely that it isn't) that's (mostly) where it's coming from.
So, about that graph:
You can probably guess what's coming next:
If you are trying to achieve a big scale up (say 5X, to quote a real recent case) in not much time (say 3 months, thankfully not the same case but nonetheless a real value) then I'd classify that as very high risk. (That's the bottom right hand corner of the graph.)
On the other hand 1.3X in 2 years is very low risk and is in the top left hand corner of the graph. (I've never seen anyone that lucky.)
So that's the graph - just another rhetorical device. But there are some wrinkles. I'll list a few - and you can probably think of a few more:
Being a Performance person I hope any fuzz in my language reflects the fuzz in the situation, not a general unwillingness to commit. If you think I'm doing the latter be sure to tell me so.
In the meantime I hope you find this rhetorical device useful.
