Yes, you're right, it is peanuts in the big scheme of things.
But what this discussion DOES do, is expose the lack of understanding of business by some posters on this board. Backlog simply refers to the amount of work signed up in the pipeline that has yet to be realized or commenced. It's not a function of time (unless specifically stated as such), other than a reflection that it's future, not past.
To equate backlog to revenues shows a lack of basic business understanding. Unless we know the duration of the contracts that make up the backlog, there's no way to know if they represent likely revenue that will be recognized this year coming up, or over the next 2 years, or 3 years, etc. Not to mention, this is especially true in the market PDSG is in, where projects can last multiple years, where there can be delays in the projects, or there is phasing of projects that create timing gaps, etc., cancellation of initiatives as funding is reallocated or cancelled. Ultimately, to link the 2 so directly is misleading at best.
