Cycle - The number tells decimate how regularly to remove a frame. For NTSC IVTC it is 1 in every 5 frames. Later you will see some examples where decimation is used differently or not at all..
Mode - The mode will govern what frame in a sequence gets deleted. This decision will affect how smooth the output will be. For a simple NTSC Telecine of anime, mode of 2 is best - you can read the decomb manual for info on the other modes.

When I started work on this video a year ago (and then forgot about it for 8 months) I didn't know about all of this stuff, so my timeline is all in 29.97fps.

Technical note: Telecide plus Decimate does not deinterlace; it performs an inverse telecine. In other words, Telecide plus Decimate restores the original progressive frames and gets rid of the duplicates created by the telecine process, which usually gives you a frame rate of 23.976 when you're done. More on this in EADFAG; I don't wish to repeat.
You can use a deinterlacer as part of an IVTC process (and most IVTC plugins do), but you should not use an IVTC solution if all you need is deinterlacing (without reducing the frame rate).
