ATTiny85; order of magnitude loss of speed when enabling map AnalogRead function

Good evening Jiggy-Ninja

Jiggy-Ninja:
To avoid further confusion, give me a ONE word answer: Based on the picture I already posted above, do you want the wave to be a sawtooth or triangle? Don't tell me the shape it is making, tell me what you want it to make.

To be precise, I would prefer the steeper dv/dt of the triangle wave for my experiment.

Please note that it is the superimposed position of the square wave which make the triangle or sawtooth wave useable for my purpose.

I am sorry for not explaining this earlier.

Please see the pic attached to previous post for a visual.
Take care, peace
