"Share buybacks can only be of shareholder benefit if there is a resultant boost in the share price creating a capital gain"
You still don't get it. As soon as the stock is bought back the capital has left the company. It can't make a gain for it. The company isn't trading in its own shares. There was never any intention for those shares to return to circulation. The sooner you get your head around this the easier you will sleep at night.
The first fundamental question is whether the company has excess capital and should return some to shareholders. Assuming the answer is "yes' (if it is "no" it shouldn't pay a dividend or do a buyback) the next question is how to do so - through dividends or stock buybacks. Either way you're just returning capital. Once you've returned the capital that's all there is to it as far as the company is concerned. Now, those that do not sell into the buyback, and thereby collect their share (or more) of the return of capital, increased their ownership at those prices and they may well lose (or gain) by doing so. But, again, that's up to them as individuals. Contrastingly, those that did decide to sell and collect their pro rata share (or more) of the return of capital will have had a different result.
With a buyback the board needs to decide on the process which will determine the price paid. There are many ways this can be done including a fixed price tender, an open tender, or daily VWAP replicating purchases. The last one is the 'easiest' (= most easily defendable) because there's the least singular-day impact on the stock price i.e. the idea is to be a buyer but not a direct influencer of the price. In any scenario, what the stock price during or after the buyback is utterly irrelevant for the company as a whole. It is only relevant for individual shareholders - but they face that relevance on a minute by minute everyday basis as they choose to buy, hold or sell as the shares price moves.
