Speed Formula and troop influence not working as the formula intend it?

[Cosmos_Shielder]

1001 troops walking in the desert are walking at 8.545 for the moment instead of 25 with 0 troops
Let's do some calculation :

$troop_influence = (pow($troops, $terrain['troops_influence']/200)/100); #capped at 0.99
$speed = $speed * (1-$troop_influence);


$troop_influence = (    1001^(100/200)   )    /100   =   1001^0.5   /100   = 0.3163

$speed = 0.25 * (1-3163)= 0.25*06836 = 0.17 = 17 meter per minute.        Did this formula have been divided per two?

[Cosmos_Shielder]

Since nobody answer , i've been told exhaustion reduce speed now. Maybe the divided by two comme from the exhaustion?

If you moved on quick march earlier, the exhaustion will surely cut your speed by half for the period of 470 min.

If you moved on quick march earlier, the exhaustion will surely cut your speed by half for the period of 470 min.

Are you positive of the 470 minute recovery period???  This is the second time I have heard that number mentioned, but my recovery period is always 540 minutes.

eeee... that can be 570, actually, I am not sure  Damn long anyway....
