Seeded Drawing

Updated: 2015-12-21

Use seeded drawing when you want to use external parameters, such as ranking or results from previous stages, control the drawing process. Click on Draw / Manage Start Times on the page Classes, and select the method Seeded start groups.

First you must specify a source for the seeding. The options Result, Time, and Points use results from a previous stage. It is possible to enter such data manually by entering it (or pasting from Excel or similar) in the columns Place in, Time in, or Points in of the table on the page Competitors. The option Ranking assumes that ranking data is imported. Competitors without a ranking are placed after all ranked competitors.

Next you have to define the Seeding groups. You can specify a single number, which means the class is partitioned into a number of groups of this size. The number 1 means that each competitor is placed in a singleton group, and that in principle no randomness is involved in the drawing. (some randomness can still be involved when seeding data coincide for several competitors).

You can also explicitly list the group sizes. If you specify 15, 1000 you get a seeded group with 15 competitors, and the remaining competitors are drawn as usual.

You can prevent competitors from the same club to start on adjacent start times by checking this option. If the seeding result in two competitors on the same start time, the last of them will be moved down the list until the the conflict is resolved. If a single class dominates the club, it is not sure that the conflict can be resolved. MeOS will return a start order anyway.

Usually, the best seeded competitors will start last, but if you want to reverse the start order you can do so by checking Let the highest ranked start first.

Start pairwise means that competitors start pairwise.

Check Assign bibs and specify the first number of the class.

Seeding does not seem to work

It seems like the seed drawing in 3.3 Beta ends up assigning individual starts at the given interval rather than grouping the competitors into start groups as the documentation leads one to expect. The same thing happens whether the group sizes are 1 or any other number... clicking to group pairwise did work, so I think there is something missing between organizing the groupings and assigning the start times at this point.

The seeded method always uses individual start times. It is meant to group the competitors to ensure (for example) that ten "best" competitors start last. But the start is till individual and random within the group.

I have so for never had a request to let the ten best start at a single time together and the other at another single time. Is that what you would expect?

Yes, I have had it requested to have the X best start at a time, then the next X as a group, and so on. So I was optimistically reading this as something related to the "Grouped Start" function which does allow for multiple runners to start at the same time.

Anyway, the idea is to have a setup even for ranking, and then a following event which would have starters in groups (groups determined by ranking) on a forked course. So a hybrid of a "chase" and Farsta.

This is not a high priority though... I just made the comment based on my incorrect assumption of what the Seeded Start Groups was supposed to do. I can do the same thing manually by printing the ranking and assigning start times to the groups in order.
