Yes, initially the pot would have been unstable on the stand if I had left it. The stand is indexed to fit the pot bottom securely. So when the pot and stand are setup correctly it is solid.
Testing so far seems to indicate that between the windscreen and pot stand, its a fairly reliable set up. By that I mean, I haven't been in a situation yet where I have been unable to get the water to boil. (after I made the modification to the pot stand) Also take into consideration that with a boil time at about 7 minutes and loss of usable flame from an esbit tab being around 12 minutes, you should have no problems getting it to boil. Try to find a slightly shelter spot, a dip, behind a tree, make a little one from rocks and it should be fine.
Sorry for the delayed response but I hope this helps.
