Refer to slightly revised schematic 0505.gif.
Looking at first set of scope shots 095~100.gif: in 095 R2 and V(C5)
were adjusted to show T1 primary going into saturation: the typical
exponential-type of current curve - stopped at exactly the maximum.
In 096, the same was done - note R2 was lower for a shorter Q1 ON
time - what is puzzling to me is that the peak sat current is higher -
?because of higher V(C5)?
In 099 i made C(V5) higher - note the peak sat current abruptly
falls, then sags.
In 100 the time is at a "minimum" and i increased V(C5) to max.

Next set 103-105.gif, kept V(C5) constant and twiddled R2; note same
peak sat current abruptly falls, then sags - in 105 it sags out of
saturation and one sees an "inverse" ramp.
**
Next set 106-108.gif, again kept V(C5) constant and twiddled R2; note
T1 goes into saturation in 107 and 106 but never peaks out.
