You are correct Bob. LH has a move of 20p (20cm). Troops cannot cross the front of enemy unless moving into contact within the enemy's move distance. This is on a recommended board size of 120cm.
Is that so unreasonable given it is modelling a 1:1 situation (1 pace = 1cm)?
I am no horseman but they seem to cover ground quite quickly when on the move! I don't think they'd be static that close to the enemy. Just trying to imagine the scenario in my mind's eye.
Anyway, I made some top down markers from the Junior General webpage to try it out over the weekend.

With regards to your comments on horse movement. I am a horseman (My Father ran a riding stables and I was an instructor and groom). Horses can cover ground very quickly. However the problem can come with turning. The larger the horse the more difficult it is for it to turn at speed. It all has to do with the "Leading leg". When a horse canters (or gallops) as it starts off it leads with one of it's front legs, usually the right or offside leg, as horses like us tend to be predominantly right handed. This means when galloping the horses right front leg goes forward first on each stride. 
This means it is easier for the horse to turn to the right at speed. If he tries to turn sharp left his leading right front leg could cross the left front leg causing a stumble or worse. In nature a horse will naturally change its leading leg in mid stride to enable it to make swifter direction changes, however when being ridden the animal has no way of knowing where its rider will wish to go, so it relies on the rider to tell it when to change leading leg, this requires a well trained horse and well trained rider. It is accomplished by pressure from the riders calves, to change leading leg from right to left apply right leg pressure just behind the saddle girth and left leg pressure just in front. This can also be done at the start of the gallop to get the horse to lead off with the riders chosen leg.

It also has to be remembered that the faster a horse travels the further up the horses neck towards his ears his centre of gravity travels. A Jockey rises well forward at the gallop to position himself over the centre of gravity and thereby helping keep the animal balanced.

These actions are now included in modern dressage, in fact almost all elements in modern dressage derive from combat manoeuvres employed by well trained horsemen in battle.

Not sure this helps in a wargame setting but hopefully interesting all the same.

I had read somewhere that Phil was no mean horseman. I may be open to correction but I have a feeling he competed in eventing.

 I have spent many a summer on Dartmoor. Although infrequently I have seen the sun there, shade is few and far between! My holidays were walking ones so no horses to be bothered by the heat. 

I seem to remember doing an escape and evasion exercise there when I was in the RAF, and it rained hard incessantly. We all came to the conclusion that capture by the enemy was by far preferable than escaping to be drowned by the Devon weather! As I recall we were supposed to be evading a bunch of Territorial Army lads. In fact we trudged about for hours trying to find them so we could get "captured" get inside and get a cup of tea!

I got very intrigued by DBV about 10 years ago. I played a few games and have intended ever since to get more into it. I had about 20+ figures painted an mounted for it and many more in the works. However, being a solo effort, I didn't really have to the drive to do more with all the competition from other projects.

I copied the rules off the website and formatted them in Adobe InDesign. I made a few changes, such as making blade/spear/foot knights move at 8p, rather than 6p. I thought it odd to have a measuring stick marked out in 4p increments and then a need to use 1 1/2 of them. I also went with 25mm wide for the basing, rather than 20mm. Today's minis are just bigger...

There are some unfinished aspects to the rules, such as elephants and chariots. Assuming PB never gets around to fleshing those out, you'd need to work out some house rules to cover them. One issue for them is that the system is a lot like DBA/DBM in that the frontage of the bases should be the same. With single models on a stand it's kind of impossible to have the foot frontage match the frontage of an elephant or chariot.
