I think you are right about timings of 4.3 and 4.5. On my Athlon-MP2000+ both 4.3 and 4.5 take the same time, 206 sec. to complete the [336, 100-111T] example. Most likely another process slowed down my 4.5 client on P-4. Will try again later.

But how can we know when to use 4.3 and when 4.5 so that we don't waste any time? Since the difference between the two versions is very small I still think that a command-line switch is a better way to handle them (instead having two executables).

BTW I wrote a script in bash to run octo for a range of exponents. It's in attached file mocto.txt. Rename it to octo and use it as
./mocto nmin nmax [kmin] kmax

kmin and kmax are in 10^12 so one can get rid of all zeros. If kmin is omitted then kmin=15. For example
./mocto 52 55 1
will test n=52, 53, 54, and 55 to 10^12. Likewise
./mocto 52 55 100 200
will test the same n's between 1E14 and 2E14. No changes to "octo" are needed. It now runs "octo45", change "exe" variable on line 10 to specify another executable.
