Presence is a time and chunk based claiming plugin.
The score rises the longer a player is within a chunk. The player with the highest amount within a chunk will automatically gain access to the chunk, while others will be denied entry.
No Placeholder API exapnsion is required for placeholders and PAPI needn't be installed in order for this plugin to work, though using it might be benificial. All placeholders require the player scope to be known, so they may not always be usable.
%presence_claimowner%

%presence_ownerpresence%

%presence_claimsuccessor%

%presence_successorpresence%
Obtains the presence of the follow-up leader of the chunk the player is currently standing on, returns "0" if not applicable
%presence_playerpresence%

Due to the chunk-based approach of the plugin, it will be relatively optimised. I try to optimise other aspects of the plugin, however from time to time this simply cannot be done logically so I would gladly accept any results from profilers (again: Timings will usually not be too great of a helper there)
Please note that this plugin is very early in it's public development phase, a few bugs may exist and I strongly recommend you to report these
