Djem so vs other styles

OT: personally Form V doesn't make any sense to me. Any style that relies on strength and heavy hitting would require huge swings which an opponent could easily counter just by leaning back slightly.

High-strength swings is not the same as telegraphed or shallow.

However, to get sufficient strength, some telegraphing is expected. It's not as subtle as say Makashi or Soresu.

But there are two versions of Form V, anyways.

A style that involves strong swings will naturally also include feints and the like, or movements that mislead as to where the strong swing is headed.

That's a strong assumption. What evidence are you basing it on in this particular situation?
