Rungs beside Tile Dock
The rung table is site-wide. Tile Dock does not own a private ladder. The floors the server uses are 0, 90, 210, 370, 580, 850, 1190, 1610, 2120, 2730, 3460, 4320, 5320, 6470 and 7780 XP. After the last listed floor, the step stays at the gap between 7780 and 6470, which is 1310 XP, and repeats.
Worked examples
0 to 89 XP is rung 1. 90 XP is rung 2. The bar on the account page shows progress inside the current gap, not the lifetime total, in the width of the bar. The numeric XP is the lifetime total. 5 XP from a spin on Farm Riches moves both, until the day cap.
A daily grant of 50 XP from 40 lifetime XP lands at 90 and becomes rung 2 in the same write. A grant of 50 from 0 lands at 50 and stays on rung 1. The streak extra can be the difference. Do the addition before you assume the rung moved.
What a rung changes
The digit on the account, the width of the bar, and the marks on the rungs page that test 90, 370 and 850 XP. It does not change Tile Dock locks. Ancient Rome stays open at every rung. Enchanted Castle stays closed until an account exists, including an account still on rung 1 with 0 XP.
Marks that are not rungs
The two-day streak and the seven-day streak read streak. The daily-grant mark reads the stamp. The day-cap mark reads dailyXpToday. Those can be open on rung 1 if you claimed twice inside the 48-hour window or spun twenty times. They are listed on the rungs page because the account can actually set them.
