SAP variable values are specified in a proprietary MDX clause appended to the original query. Analysis Services parameter values are passed separately from the MDX query, and are evaluated at the server.
So...keeping that in mind, if you look at the palm of your hand -- all of it, from where it meets your wrist, all the way around (except the fingers) that is about the same size as 3-4 ounces of steak. So, twice that much would be 6-8 ounces. Don't forget -- that's UNcooked. When steak cooks, it gets smaller.
The theory is that a seasoned cook can tell how well-done a steak is by poking it with their finger. If it's rare, it should feel like the fleshy part of your hand at the base of your thumb when you touch your thumb to your index finger. Medium is if you touch it to your middle finger.
