Refactor variables into functions

[jenny-ccc]

I would also suggest moving totalSeconds excludeIds and subEntryIds into functions:

e.g. for subEntryIds

private Collection $_subEntryIds;

public function init(): void
{
  $this->_subEntryIds = collect();
}

protected function getSubEntryIds() 
{
  return $this->_subEntryIds->toArray();
}

protected function trackSubEntry(int|array|Collection $id): void
{
  $this->getSubEntryIds()->merge(collect($id));
}

then you'd just do:

$this->trackSubEntry($id);
