Alien Land Speed

Just what exactly is the km/h speed of a Cryssalid?

 

From what I can tell is...

 

Each Cryssalid has, if I remember, 120 TU.

The average street square takes about 4 TU to traverse.

Each tile is, judging by how it can hold one crumpled human form, about 2 m in width.

 

120 * 2 * 0.25 = 60 m per turn.

 

Now...how long (in s) is a turn? Before, I had guessed it was about 4 s (can get off about three autofire bursts per turn) but that would clock the Cryssalids at about 900 m a minute, meaning 54 km/h...

 

Does that sound accurate...?

Actually a square is only 1m wide. Look at it when the human is standing not crumpled as a corpse. When they fall down dead they do not lie down they simply fall as if all of their bones were removed from them. Their knees and elbows also overlap the edges of the square slightly...

 

As for the length of a turn it is most definitely not four seconds... These soldiers are presumably moving in stealth and they move a long way. I personally would say it's more like 10 seconds per go.

 

That would give the Chryssalids a much more realistic speed of 10.8km/h, approximately 7mph

consider, if you will:

 

our top atheletes can run at approximately 10m/s

 

there are approx 1600 meter in 1 mile (afaik)

1600m / 10m/s = 160s

160s / 60seconds/min = 2.67 mins

 

60minutes / 2.67minutes/miles = ~22.4 miles

 

thus our top athletes run at about 22.4miles per hour

 

i my self walk at about 3-4 miles an hour, but thats a pretty leasurely saunter.

personally i'd think that chyrissalids (as they are supposed to move scarily fast) would be able to challenge our top athletes.

As far as human energy is concerned. It takes far more energy to get from A to B in complete silence than it does to just sprint there. Trust me! Chryssalids are supposed to run extremely fast but I don't think the speed we're calculating is their running speed. I think it's their casual walking speed. Have you psi'd a Chryssalid for subsequent turns? It takes a helluva long time for theuir energy to run down. I don't know why they wouldn't run while they were in a battle but still, humans don't run away from them in the geoscape and they have only half of a Chryssalid's top speed. So why bother running?

 

I'd like to see anyone in the world capable of running top speed for an hour Alan. :( The three minute mile is not only for athletes though. A lot of people in the forces can travel a good three or at least four minute mile... Doesn't mean to say they won't pass out at the end of it but so would the world's best athlete if he kept going for 22miles! :(

Fox, that's just not comparable to home-cooked Kraft Dinner. I have no idea why nobody imports dried macaroni and cheese powder to Ireland, but I haven't found it yet, and I'm sad.

 

Ontopic: Vet, my guys would run when I tell them to run, but it is animated as a walk. Probably because of all that standard equipment. The stealth would come in when they stop and use reaction fire. I wouldn't sneak across an open area exposed to enemy fire, I'd run for cover. But anyway:

 

I'll use Vet's 1sq=1m assumption and Snickers' 4 TU/m requirement to cross pavement. I'll use metric.

 

120 TU's will get the Chrys 30m in one turn.

 

Idle internet discussion puts 10km/h as a strong maintainable walking pace for a fit person and top athletes able to run ~30km/h for short distances (400m Olympic events).

 

11km/h = 3m/s

36km/h = 10m/s

 

The Chrys at 30m in one turn, if we give him the 36km/h speed, implies a 3 second turn (30m/10m/s). This works if our average soldier marches 3x3=9m, 9 squares down the street in one turn and spends 9x4 = 36 TU to do so.

 

So can someone confirm the average (rookie) soldier TU's?

If it's higher than 30-40, either the turns are too short or our soldiers are running faster.

 

I keep wanting to ask "African or European?" but that's a different offtopic...

Your average rookie has something like 55 TUs (min: 50 max: 60), and just to put it into perspective your generic civilian has 35 TUs.

 

That's not going to explain why the earth is banana shaped, but there you go.
