I do not think it has ever been made clear if the stack bonus is cumulative for each unit, or is a flat bonus for the entire stack. Nor do we know precisely what the maximum stacking bonus is, just that the maximum stacking bonus is achieved at eight units.
I apologize in advance if this observation has been made before. I have not seen it in the wiki, and there are A LOT of posts that I have not read through, which means I have likely missed this speculation if it has come up before.
For example, lets say that the stack bonus is +1 for every unit beyond the first up to +7 for eight units. Let us also assume there is a stack of eight doombats, and assume that a doombat has a combat/attack rating of 1. Given these assumptions, the entire stack will have a combined attack rating of 15 if it is a flat bonus (1 * 8 + 7) and 64 if it is cumulative for each unit ( (1 + 7) * 8). The former sounds much more reasonable, given that piling on more troops was described by parson as being Additive. If the latter was true, almost any group of eight units could easily croak, say, a dwagon (unless of course a dwagons combat rating really IS that high), which probably isn't the case.
Also, the flat bonus system would encourage maximizing the number of eight unit stacks, which is precisely the behavior that we have witnessed. For example, using the scenario above, lets say we have 16 doombats. Under the flat bonus system, two stacks of eight would yield a combined attack bonus of 30 for the entire force (2 * 15) versus 23 if they were in one big stack (1 * 16 + 7), while the cumulative bonus system would result in a 128 rating for two stacks (2 * 64) and the same for one stack ((1 + 7) * 16). Thus, the latter system has no incentive for maximizing the number of stacks, just minimizing the number of stacks with fewer than eight units, while the former system provides an incentive to maximize the number of eight unit stacks, unless there is some cumulative bonus that can be applied (such as stacking with a warlord) that would be greater than the opportunity cost of the stacking bonus from splitting up the force into multiple stacks.
Thus, when doing the mathamancy to determine an individual's Combat rating from this Summer Update, one should probably not add in the stack bonus, as it probably is included in the stack's full attack rating, not individual unit's combat ratings.
All of this mathamancy also implies that there is a maximum limit on the size of a stack, and the number of units/stacks in a hex. Otherwise, all of the units could be in one giant blob of a stack to get Ansom and Wanda's stack bonus and smash face.
