These simulations are as accurate as the Software in which it was created. These are simulations ONLY !! , created for Training purposes.
It is essential, that the beginning of each cycle is used, when checking these simulations  for accuracy, .
These simulations may not meet the accuracy intended by the authority.
When navigating, a reliable timepiece should be used,  with the appropriate Light List.
