There is a TD Tip after rule 5C that has a note that states:
“Note 3: If an event or section(s) within an event have different schedules that merge, the rating report submission process now allows the director to include the time controls for each schedule.”
This makes it seem like you could list the time control for each schedule (and list who was in each schedule) and the programming would rate each schedule according to the time control listed for that schedule (I know this isn’t how the programming works).
Until MUIR can be changed I would guess these tournaments can be handled by keeping a copy of the pre-merge quicker sections, changing the post-merge games from those sections to non-rated results, and then rating the pre-merge sections at one time control and the reduced post-merge sections at another time control.
If there was sufficient interest in it (which is unclear), it might be something the pairing program authors would add, what I would call a linkage rather than a merge, an option where for pairing and standings purposes, including tiebreaks, two sections are treated as one merged section, but for reporting purposes they remain two separate sections, that way there’s no post-event fiddling around needed to submit the rating report.
This need not be only for events that fit into different ratings systems, we ran our city championship one year as several RR flights which seeded into two or three 2nd level RR flights, with total standing from both the prelims and finals being used to determine the champion from the championship section. But because this took about 3 months overall, we submitted the first set of RRs for rating long before the second set of RRs was over.
How does that note not accurately describe the MUIR setup? Can you not put in the time control by round/schedule when you are submitting a tournament for rating like you could prior to MUIR?
No, at this time the MUIR time control parser only supports one time control, it gets confused if there is more than one. Whether that will be changed at some point is unclear, A few years back the office permitted TDs to just put in the slowest time control rather than enter a lot of data that, practically speaking, is not used for much.
