Oh!! This change of setting is work!!
checkcumstrands=1 ;1=active, turns on limiting for cumstrands
;---------- outside of bounds cunstrand options ---------
deleteout=1 ;1=active, will delete cumstrands that are outside of the specified window, probably not needed so default disabled
deleteoutinterval=30 ;interval wait in frames when feature is used
deleteoutx=-30 ;the left side of the window to delete strands
deleteoutx2=800 ;the right side of the window to delete strands
deleteouty=800 ;the bottom side of the window to delete strands
deleteouty2=30 ;the top side of the window to delete strands
;---------- frames per second cumstrand options ---------
maintainfpsfromcumstrands=1 ;1=active, will fade cumstrands to attempt to satisfy fps target
maintainfpsfromcumstrandsinterval=5 ;interval wait in frames when feature is used
desiredfpsfromcumstrands=18 ;0+, the desired fps target for cumstrands to start fading, is overwritten if checkautofsp is active
numberstrandstoageforcumfps=2 ;1+, the amount of cumstrands to fade at the same time when fps target is met (higher value results in faster fps normalizing by deleting multiple stands at the same time)
cumagingfpsamount=30 ;1+, the amount of age per frame that is added to the oldest targeted cumstrands (higher value results in faster fps normalizing by deleting the selected strands quicker)
;
;---------- alpha cumstrand fade options ------------
fadecumstrandsoflessalpha=1 ;1=active, kills almost hidden strands quickly, good to remove almost invisible stands hogging cpu time
fadecumstrandsoflessalphainterval=1 ;interval wait in frames when feature is used
fadecumstrandsalphalevel=0.25 ;0.0 to 1.0, alpha level to start fading strands quickly
cumalphafadeageincreaseamount=-20 ;rate that strands fade
;
;----------- constantly fading all cum strand options -----------
quickercumfadeall=0 ;1=active, fades all cum quicker
quickercumfadeallinterval=1 ;0+, interval wait in frames when feature is used
quickercumfadeallamount=-0.9 ;1+ amount added to all cum strands age each frame
;
;----------- constant defined cumstrand fade options --------
constcumfade=0 ;1=active, fades strands after desired amount at equal amounts
constcumfadeinterval=1 ;interval wait in frames when feature is used
numcumstrandsdesiredconst=10 ;number of strands on screen until feature activates
cumagingbasconst=-0.9 ;amount added to age
;
;----------- linear cumstrand fade options ---------
linearcumfade=0 ;1=active, fades strands after desired amount linearly compared to creation
linearcumfadeinterval=1 ;interval wait in frames when feature is used
numcumstrandsdesiredlinear=1 ;number of strands on screen until feature activates
cumagingbaselinear=-0 ;bonus amount always added to age
cumagingmultlinear=-0.5005 ;multiplier of linear amount added to age
;
;----------- quadratic cumstrand fade options --------
quadraticcumfade=1 ;1=active, fades strands after desired amount quadratically compared to creation
quadraticcumfadeinterval=1 ;interval wait in frames when feature is used
numcumstrandsdesiredquad=1 ;number of strands on screen until feature activates
cumagingmultquad=-0.007 ;multiplier of quadratic amount added to age
cumagingbasequad=0 ;multiplier of quadratic amount added to age
;
;----------- instant cumstrand kill options ----------
cumstrandkill=0 ;1=active, will remove older strands after limit is reached (no fading, instant remove, good for defining absolute maximum of cumstrands, but looks bad)
numcumstrandsdesiredkill=50 ;number of strands on screen until feature activates
;

I have tried using negative values on strandlimit mod, but the cum will still fade out or disappear at the end. All I can do is extend the lifespan of cum.
