That’s what I’ve never understood and why I’ve never got into the power leveling. Please explain these rules...
I mean, It’s imaginary game currency that you always get more of in *an hour*! Players get bent out of shape, I revert back to the original “intent” of the game, kick them from the guild and a go hunting for their neighborhood to attack and plunder...
It's an agreement between players. To be in the thread, you follow the rules of the thread, and there's significant advantages to being in the thread (fastest way to level your buildings). The only constant rules are
if it's a "190% thread", when you post your building 190% is safe to lock the spot
if it's a "190% thread", you give "190%" when you claim a spot, regardless of whether less would lock it or whether your arc bonus is lower
claim in the thread before you take a spot, the first person to claim gets it, and drops the points immediately
other rules may include things in respect to timeframe, or how to settle mistakes (which will happen).
All of this should be explained to you before you're added to the thread. When people understand how they work they're no more complicated than FP swap threads (which regularly get messed up too by newcomers who aren't educated first).
I've no doubt some people take it too seriously, but usually mistakes are met with polite reminders.
