Yes, it is, thanks.

Yes, that is right.

It is effectively a counter that you can't see before the main counter
with the carry-out point set to a variable position.

The frequency of the clock is "divided" by four in 1:4 mode.  So 1MHz
clock becomes 250KHz.  Remember that the timer clock is instruction
clock divided by four already.  You get 1MHz timer clock from a 4MHz
instruction clock.

1:1 is basically no prescaler at all.
