Being a coaching an into player development etc as well as a bit of a stat nut I thought I'd throw together the following to compare and see how sides go across the year. I will do a second stat compilation on birthdate ala Outliers but just wanted to compare schools on age and time at school (Importiness Score or IS). The major shortcoming of this info is that it is based on the schools official First XV squad. Obviously each school has different size squads and there is also the issue of U16s bringing the numbers down.
The data processed was 1. Age 2. Time at school
Age: Under 16 eligible players=16
Under 17 Eligible= 17
Under 18 Eligible= 18
Pretty simple. So an U16 A team would score 16.0, while a traditional open team with zero repeats or year older kids would score 17.0 etc.
Time at school (IS) was scored as their enrollment date.
2010=0 years at school
2009= 1
2008=2
2007=3
2006=4
So a team of players who have all been at the school since year 8 would score 4.0 etc.
One would theorize that the oldest teams would be the most successful while the teams with least time at school also the most successful. Again please note that these are based on squads. So perhaps one school might field all 18 year olds in a match day XV but are ranked low on age here as the rest of squad is 16.

It is always the likes of TSS and ACGS that get tarred with the 'import' brush, but what about TGS? 2nd oldest squad with short time at school. Interesting to see that the age at time at school correlate for some eg IGS, NC, BSHS, BBC, GT.
