THE higher you go in rugby, the finer the margins become.
Coaches are desperate to uncover any advantage, no matter how small, and the use of video analysis is one tool helping them do that.
The stars of England and Gloucester employ a whole video team armed with the latest equipment and software to break down all of the various elements in a match.
But what of the amateur sides that do not have that backing? They have to make do as best as they can.
In National One – the last bastion of amateurism before the professional ranks begin in the Championship – Cinderford are using a family business for a video edge.
Once head coach Dave Pointon hung up his boots, he was employed by the Cherry and Whites to film matches and analyse them for then bosses Nigel Melville and Dean Ryan.
Now a second generation of the Pointon family is treading in the footsteps of the St Peter's High School director of rugby.
While Dave's youngest son Danny plays for the Foresters, brother Joe films all home games and captures the action from a specially-built hut on the halfway line.
Having played for Gloucester's Colts and Old Patesians and now in his second season as Cinderford cameraman, Pointon junior says video analysis is becoming a vital aid in the ever-developing sport.
"If results aren't going your way then you can break games down and realise why they're not going your way," said Joe.
"Especially when players are not performing, you can see why.
"Why was that penalty given for that scrum? Why was our prop beaten? Why did we lose that lineout and why did the backs get beaten?
"It's not just a case of putting the game to video, you have to have the eye and know the technical stuff.
"That's why my dad is so good at it because he has the technical rugby nous.
"Technology is a bit of a hobby for me and I like gadgets but with my brother and dad here at Cinderford I like to be involved too.
"With not playing anymore I still get a bit of a buzz on a Saturday.
"You get an appreciation of the skill and become even more analytical.
"You see that a player should have given a pass earlier or not kicked it away.
"You get a different perspective to the supporters or players because you're analytical.
"Within 20 minutes of the final whistle, we'll give a copy of the game to the opposition coaching staff and referee.
"Then the day after a game my dad analyses it and goes through it writing notes and picking out bits and then we'll do another DVD of just the highlights.
"The restrictions of what we do are time and money.
"There are systems that would be great to use but the cheapest you are looking at is £2,000."
