Basically, to cut a long story short, I wanted to put in a fancy equation to predict those results to show my lecturer that I've thought outside of the box a little bit 
I know it isnt going to be particularly accurate, I just want an estimation based on the data that I have, is the method that Steve gave correct?

Just do a line of best fit graph.
Excel calls them trend line.

^^ so essentially your saying you want to fake results as your application was struggling to handle 50 users  but you'd like to make it seem like it could handle 1000?

No I'm going to admit that I only tested it with 50 users, thats all part f my critical appraisal of the project, but then im going to go on and make some estimations

plus (not knowing what you've made / testing) - surely say 1000 people are using it in real life, they wouldn't all be doing requests at the exact same point of time. I know myself with software calling upon databases, they do very quick queries or updates to the database and then cut the connection again. So the person may only be connected to the database for a split second. Thus the chance of say 100 users actually requesting from the DB all at the same point is nigh on impossible, most likely it'll be rare for even 2 to be doing the same at the same time.
The only thing I'd advise is making sure the application definately 'disposes' of the connection. One piece of software I wrote for my current company, I found that when I got up to about 10 + users, it started going slow / requests were taking a while etc. I couldn't understand it as I had written in my code for the program to close the connection after each action. However, unknown to me the software / database kept linked regardless. So by the time it got to 10 people or more there were 10 constant links into the database, causing lock issues and slowness.
I had to dispose the connections to sort it out. Could it be something like this which is causing errors at 50 users?
