Tetenal does not give advice on manual agitation in their manual, though they hint at manual small tank processing.

Kodak says: first 30 sec continuous agitation (1complete reversing cycle/sec); then dumping into the bath for each 13 sec followed by 2 reversing cycles.

Agfa said: first 30 sec continuous agitatation; then 1 movement (complete cycle I guess...) / 30 sec

So, we have 4 cycles within 30 seconds against 1 cycle within 30 seconds...
