When any kind of repeat block ends, it creates lag. If you copy and paste the contents back into it, the speed will increase. The order goes like this: 4x repeated; there are 4 movement blocks. 2x repeated; 2 move blocks 1x; 1 move block 1x + wait; 1 move block and a wait 0 block The 4x cat gets 100% to the end. The 2x cat gets 50%. The 1x cat gets 25%, and the 1x+W cat gets 12%. This was tested in turbo, normal, fast flash blocks, flash, flash turbo, and java. All tests were identical.
