Gravity point drop equating to X %ABV

Ok, I'm gonna post a table as best as I can (I know sweet FA about CSS, HTML and the other kinds of shit needed for this - I'm copying some shit from google). The point is, is that I'm obviously being a bit thick, as I haven't worked out how to use the "mead calculator" over at gotmead. Fine. So I'm putting this table up, the data having been produced by the unfeasibly helpful Bob Morton, who runs WinesatHome, because it's just a bald list of how much alcohol you can expect from a certain drop or difference between a start and finish gravity reading. It takes nothing into account, not any possible variations of sugar content from different honies, etc etc. Just that if you measure X as your start, Y as your finish, then the drop in gravity will equate to a %ABV reading from the list. I believe it also works with multiples i.e. if you start at X gravity, let it drop say 50 points to Y gravity, then you step feed some fermentables back up to (lets call it) X1 and then let it go to the fermentation finish of say Y1 and the drop from X1 to Y1 is equal to 100 points, then you've had a total drop of 150 gravity points which also equates to Z %ABV. I hope that makes sense, I certainly find it easier to work out the strengths of my brew with a reasonable level of accuracy. Oh and I'm only listing the %ABV to 2 decimal points, and not 7 as Bob did with the original data. If you want to be that anal and go to that level of accuracy, then you'll have to register at wines at home and get Bob's original spreadsheet. Edit...... Ok it turned out to be a complete pain in the arse to input the data as a pretty table, so fuck it, here's the data, just as a long list...... The first column is the difference or drop in gravity, while the second is the % alcohol that the drop in gravity represents.
