Feb is in two different seasons, with the first half (plus one day) in season 4 along with mid-June thru Aug, and Oct and most of Nov. The second half is in season 6 along with March and most of April, and Thanksgiving time.
That second half of Feb sort of makes sense since time around the Presidents' Day holiday and the Princess half-marathon weekend are always in the second half of Feb. The Thurs to Sun of that marathon weekend has traditionally been the highest DVC demand time at WDW that exists between mid-Jan and late Sep, and holiday time usually has somewhat higher demand during that period than other times.
The part that is somewhat questionable is the first half of Feb in season 4. Feb 1 to the Thurs before Presidents' Day has traditionally been the lowest DVC demand time of the year at WDW. However, also questionable is including July 7-31 in that same season 4, since July 7-31 happens to be the second lowest DVC demand time of the year at WDW. Ideally, that earlier Feb time and July 7-31 would be in season 1 where Sep 1-19 sits, which Sep period has actually traditionally had higher demand than that early Feb/most of July time.
You may be aware that substantial point shifting has occurred in the last two years, where points have been moved, via a change from a 5-season to a 7-season chart, mostly raising points needed per night in the Fall season, while lowering them mostly in the May through Aug periods. As long as total points needed to reserve all the rooms in the entire year remain unchanged, such point shifts are allowed and arguably even required to meet substantial changes in seasonal demand. However, there are limits to how much each day can change, up or down, annually, which would make it difficult to get that early Feb and most of July time in a lower season than they are now.
