Good on you Lee

,
Just having a quick look and if you used Yeasty's file, everything looks great. I suspect that you are actually within 3% of what was predicted but some of your terminology is a bit unclear so I can't be sure. [EDIT: Ignore this

- see next post for why.]
I'm the site's terminology PITA so I might as well be the one to ask...
What do you mean by fv? It might seem obvious to you but it isn't to me and I have been brewing for years. Do you mean, 'fermenting vessel', 'final volume,' 'finishing volume,' or something else?
The important thing to communicate on a brew, assuming you have done no post-boil dilutions or fermentable additions, is EOBV-A. This is the end of boil volume at ambient temperature. Which is the same as your...
VIF plus KFL = (Volume into Fermentor + Kettle to Fermentor Loss)
Unless we know your EOBV-A, we can't really tell or advise much. We are forced to guess. My guess is that you were actually very close to Yeasty's prediction and set-up and I would be very reluctant to change anything for your next brew without more detailed info.
Does that make sense?
