Idle position during landing

Hi,

When the A/T is ON during the landing I find that the idle set position is pretty long. What do you think about that?

Normally the idle position comes pretty fast to engage the reverse. In my case I have to wait 3 seconds after the touch down to engage them. ( the time that the throttles come completly to idle). The idle position could be set between 30ft and the touchdown.
