Best / Consistent Clubs last 10+ years

Curious to see who have been the most consistent clubs over the past 10yrs.
Who fly under the radar?
Who climb the divs well?
Who spiral down?
Think i've got it accurate..
Best:
Goodwood - only club to remain in D1 since 2011. Next best Rostrevor (promoted 2012).
North Haven - gone from D5 in 2011 to D2 2022. Never relegated during that time frame, promoted 3 times.
Westminster - after dropping from D4 to D6 in consecutive seasons, have worked back to D3 and remained for 6 seasons.
Glenunga - D6 in 2011, promoted 6 times, now in D1.
Worst:
Gepps Cross - D1 in 2011 / 2012, been relegated 5 times since then, currently D5.
Eastern Park - D1 in 2011, relegated 4 times including 3 in a row, currently D5.
Greenacres - D4 in 2011, relegated 3 times, currently D7.
Yo-Yo's:
Woodville South - Promoted 4 times, relegated 3 times. Went D6 > D5 > D4 > D5 > D6 in consecutive years.
Kilburn - Reached as high as D2 in 2013, now D5. 3x promotions, 4 relegations.
Rosewater - D5 to D6 and vice-versa 5 times in 12 seasons.
Interesting, clubs who seem to rise rapidly (i.e.consecutive seasons) don't often last before they drop back.
