As pointed out before, this method works to some extent, but is has its limits.
You cannot reach the counter density that way which you might need to fit a large OoB into the available 400px offboard margin.
Furthermore, that method does not take into consideration, that it is not only counters which you want to place and align offboard. You also want to place and algin counters in relation to Labels, which can be more than a string of letters but also more complicated HTML frames. The hex grid in such cases will not suit your needs:

What you see above is a "Label" which contains HTML-code. A number of counters are placed on that Label. While the above shows the "best efforts of 15 minutes" to place the counters using v6.6.8 (i.e. nigh impossible), this example still illumines why placing an "extra board" to serve as an offboard area is not a solution. A placement of counters suited to the needs of this "Turn Track, Weather, SAN Area" is impossible to be served by any onboard-grid (using an extra board to create a pseudo-offboard area would necessarily implement an onboard-grid to that pseudo-offboard area).
