[wptabs mode=”horizontal”][wptabtitle]REVIEW[/wptabtitle] [wptabcontent]With a great number of matches taking place, the Cup getting underway and Cup entry round being confirmed, some of the most interesting changes so far this season appear in this week’s rankings:

Given Methodist College’s close win over Belfast rivals Campbell College, their place at 1st position has been strengthened further while RBAI and Campbell hold on to their closely-matched respective 2nd and 3rd positions (only 15 points different between their scores).

The first change comes at fourth position where RS Armagh have risen to their highest ranking so far this season, given their confirmation as Round 4 starters, and despite not playing an Ulster-schools team this week; in contrast, Limavady GS have dropped to 11th after a one-point defeat against Ballymena Academy (6th) and being confirmed as Round 3 rather than Round 4 entrants.

At the bottom, Larne GS (30th) have picked up form at just the right time and moved back off the bottom spot* giving that ‘honour’ instead to their defeated first round opponents, Cambridge House (31st). In Round 2, they will go on to face Regent House (28th) who are sitting in their lowest ever position since rankings began in 2007.

For those of you who keep up-to-date with Ulster Schools’ 1stXV rugby on this site we have some important news:  starting immediately this season, we have improved the formula that generates the rankings you see posted on The Front Row Union website each week.

To help understand these changes and the ranking system in general, we’ve provided a few questions and answers below that should help to make things clearer:

What is the point of the ranking system?

This system was mainly designed so that every one of the 32 teams involved with Ulster Schools’ 1stXV rugby could be ranked using the data available, without the need for every team to have played against every other.

How is the ranking calculated for each team?

The three biggest factors taken into account are each team’s win percentage (number of wins, draws, and losses), opponent rating (the strength of sides faced) and competitive rating (their progression within the various competitions), alongside penalties for inactivity which prevent less active schools being ranked higher than they deserve. The formula produces a score for each team using these factors which then allows us to rank them in order from 1 to 32.

Are points/tries for/against taken into account?

Presently, no, and probably not in the near future for two main reasons: firstly, with a lack of scoreboards at matches, fans (and indeed coaches/players) often argue over the exact score of each match, so they are difficult to confirm; secondly, the margin of victory/defeat often has to do with the opponent played, which is already taken into consideration in the calculation.

Hey, my team defeated that one! Shouldn’t we be above them?

Not necessarily: the ranking for each team is based on the season as a whole, not a head-to-head basis, so often teams can be ranked below those which they have beaten. Don’t worry though, if you’re truly better than they are it will show eventually!

What does the rating of each team actually represent?

The decimal rating assigned to each team represents a calculated estimation of that team’s ability. To put it another way, if every team played every other in a full season, the score is what win percentage would expected of each team, given the data available. This is why teams’ ratings change week-on-week even if they haven’t played; it is a comparison with the performance of every other team.

So, has scoring changed in the new system?

Yes and no: the original scoring is retained but is now understood as a rating (see previous question). However, each team now receives a second score per week as a measure of performance (simply called score). This second rating is a number between 0 to approx. 1000; the higher the number the better the performance. This second scoring system, unlike the first, allows teams to be compared week-on-week and even season-on season as the same score in any two weeks represents the exact same level of performance.

Is opponent strength now calculated any differently?

The new formula has been updated to better reflect the opponent strength faced by each team. Originally, an average was taken across the season as a whole up to that point, whereas now the average is calculated using the strength of opponent dependant on how strong they were when they actually played the team in question. This leads to a more accurate representation of a team’s performance and stops the situation whereby a team could see their performance improved/downgraded without actually playing that week.

Have any other changes been made?

Penalties for inactivity are still included but now accumulate from week to week if a school does not take part. This will help to prevent schools sitting higher in the table for an extended period as sometimes happened with the original system.

How are these numbers used to rank the teams?

Teams are placed in order firstly by score then by competitive rating, form and finally, opponent strength. If there is a still a tie at this point other factors such as head-to-head record, competitive match-ups and inactivity penalties may be taken into account, but it is unlikely that this would be needed, and has so far proven to be so.[/wptabcontent] [/wptabs]
