Descriptions

Total Tests: The total number of complete Proth tests that have been performed by the network. Dropped tests and currently-pending tests are not included in this count.

Pending Tests: The number of tests currently pending. A pending test is one that has been assigned to a client, but that has not yet been reported. Note that it's possible some of these tests have been "dropped" — the user has stopped running SB, and the test will never be completed. Eventually the system will stop waiting for the user to finish the test, and put it back into the queue for testing by another user.

n Lower Bound: The value of n at which we started testing this multiplier. It is assumed that all n less than this lower bound have been previously tested by other members of the Sierpinski search community.

n Upper Bound: The largest value of n for which it is known that no primes exist for multipliers less than n. In other words, all multipliers less than or equal to n have been tested either by Seventeen or Bust or by other members of the Sierpinski search community.

Max Tested: The largest value of n that has been tested by Seventeen or Bust. Note that this does not mean that we've tested all values less than this number; there are almost certainly lower untested numbers.

Current Test Window: This is the range of n values that are currently being tested by the SB network. There may, of course, be numbers within this range not being tested; only the minimum and maximum pending test values are shown.
