I believe that is the normal SPICE behavior, to try there first.

How many "Direct NR" iterations are allowed to run before giving up (no convergence achieved) and start using homotopies (i.e. gmin stepping, source stepping etc..) ?
It's been ages since I checked on that.? But it might be the option ITL1 = 100.

I suspect most books about SPICE will tell you.
