PbP gives 194
RS gives 135 at 461
CSII gives 65 at 461
194+135+135+65+65=594
451 gives 63 and 131 for CSII and RS, 461 gives 65 and 135. Somewhere in the middle is 64 and 133, which will complete your synth. I estimated it at around 455, I have tested at 457 and it was enough, giving 64 and 134.
The only way to finish a 4* in four steps is with PbP and 3xRS, which is a bad idea.
