How is the gain formula developed?

At saturation the voltage gain is 38*Vcc and at midpoint the voltage gain is around 19.2*Vcc.
yes, sorry, that i what i meant to say.

And i understand what audioguru meant, that establishing that gain at 38*vcc which occures when current saturated is useless becuase there is no room for voltage swing.

You'll notice that if Vcc is 12 volts, the voltage gain with midpoint biasing is 19.2*12 = 230.4. Perhaps this is the source of Audioguru's figure of 220. He did say "...with a reasonable Vcc..."; 12 volts could qualify as "reasonable".
Thank you for clarifying
