If a team employed the perfectly acceptable tactic (as you said yourself) of pumping the ball long to a centre forward in the last 5 minutes then you could manipulate the stats the way you have to suggest they pumped the ball forward every 28 seconds throughout the entire game.
Football doesn't work like that though, and there are different periods of different play in every game. For me a fairly high indication is all you can take from this data, I don't think you can conclude that they 'spent the entire game lumping it to him'.
Also, there is a big difference between targetted direct delivery to a CF and 'lumping it up to him' as you describe. But I think you already know that...........
