Wow, I really, really appreciate your comments and the way you discuss! Great game attracts great people – it seems to be the fact for Warmaster.
I have to admit that my comment was put in controversial way - sorry for that, but it was the intention. The reason behind is that I love this game... Such discussion – which is not initiated by the rules lawyer (as me), but by others - can greatly contribute to overall level of our knowledge about the game, its beauty and actual simplicity.
This is open Forum, every opinion is welcomed especially if put in the proper way – this fact is undisputable. But this movement part is really often played wrong (I'm not afraid to say it), and it might be played right when few facts are considered, I want to really keep the focus in this topic.
Of course in my gaming group not everyone is playing like that – after all we have only two, three rules lawyers

– but when we are in the tournament it is really well recognized method of clarifying if the move is allowed. This way of playing exactly according to the rules (while still keeping the spirit of the game) is commonly accepted.
Such situations happens in at least 50% of charges from the long distance, in 99% of advances when you have 10cm of movement (please note that being 10cm from the enemy does not mean you can actually charge him!) etc.
Concerning the mathematics. I started the discussion in previous thread with some calculations done in different way than Lex. But my intension form the very beginning was to show this
black arrow. Turning around is just critical example of general rule – but the discussion started in this way and now is going into more general direction. (I am going to come back to initial topic when general approach will be agreed.) There is simply no maths at all in such approach, while still it is really fair solution. When obstacles are on the way two moves are actually done. One to pass the obstacle, the second to finish your move or charge. But still vectoring is involved – just more than once.
Are there other/better interpretations? – in fact I doubt (but still might be wrong) as the rules are saying:
As a unit moves, you can rearrange its stands as you wish. Stands must remain touching but can be turned round or arranged into a line, column, or an irregular formation. When each stand is moved, no part of the stand can move further than its permitted maximum movement distance.And additional idea is “keep it simple!†So vectoring is recognized as the fastest and fair way of measuring how far the most critical part of each stand moved.
I would like to put more pictures but as this hobby part of my life I am really limited in time. Even to write this post it cost me somehow too much time (unfortunately). But Warmaster and adversaries like you are worth of that. If this discussion is ongoing I will try to prepare few more pictures to finally explain my point.
Thank you once more for all your comments!
