Indeed there is a lot of free levels challenges dealing with speed (ticks) that haven't been done yet . Until now I have done two:
Free levels Speed challengeviewtopic.php?f=5&t=2684
Free Levels Speed + Penalty Shot Challengeviewtopic.php?f=5&t=1523
If this thread survives (forum is a bit slow lately) then it will be another successful compilation of official FC records, like the "simplest solutions" thread. The fast+simple thread is not entirely "official" because it uses a specific formula to calculate the score, as there is no general way to decide on speed and number of pieces because the two factors are relative to each other.There a few others too.
