From my novice point of view: I can follow the calculations, but I only see selfcontained circuits, while they are being classified as amplifiers. Which nodes represent inputs and outputs? Are these voltage or current amplifiers? Multiple times references are made to "increased impedance as seen from base" : this is not made clear mathematically. Also "swing" is not explained mathematically (the circuits seem static except for AC feedback), I assume this is about swing in the input, if so then inputs and outputs are obscure in this article.

Perhaps an introductory section could explain the possible variations of beta in the lines of the following:

beta, although specified in a specific transistor's datasheet, has both a component dependence and a temperature dependence: in the following assume beta = beta_specific(T), where beta_specific at a reference temperature would be close to a listed beta, and the temperature dependance is increasing with T. One major issue in designing with transistors is making the circuits behaviour resilient enough to both component variability and temperature deviations...
