Most multi-year seasons/office terms/numerical ranges are acceptable, as long as the season duration/term length/range size is <= 10, and the gap between seasons is <= 6. For series exceeding either of these criteria, see/use {{Irregular navseasoncats}}.
The length of each season is automatically determined from the originating category name, up to and including 10 years. compliance is preferred, but some deviation is allowed and tracked for regular series with seasons > 1 year long. {{Category redirect}}s are followed, and tracked for either MOS contravention (to be corrected) or for navigational aid (no error). The gap size between successive seasons is also automatically determined, up to and including 5 years, and defaults to 0 (e.g. 1995–96 → 1996–97).
Automatically condensed years are supported for presidential categories only (but can be easily expanded as needed), for gaps up to and including 5 years, and defaults to 1. To skip gaps of up to 25 years in any year categories, use |skip-gaps=yes.
Unaccounted-for name+number conventions: where a fixed number is part of the prefix text, e.g. Chapter 11 bankruptcies, a non-breaking space may force the template to work. See this fix, where {{title year}} skipped over 11 as part of a word rather than a discrete number. (This has been accounted for and is no longer required in this example.)
General: for large, permanent gaps† between successive categories, use {{Succeeding category}}, {{Preceding category}}, {{Category pair}}, as needed, in addition to {{Navseasoncats}} on both sides, or in the middle, of the gap. Even if {{Navseasoncats}} is isolated, it has the benefit of confirming the absence of nearby categories to the reader or maintainer. †Permanent gaps, where there is confirmed to be an absence of data, and not just a current, yet to be filled, gap on Wikipedia.
