[Closed] Modifying Soft Selection [SOLVED]

Hi.
Is there anything I can do to speed up setting nonzero values?
The goal is to have soft-selection without actual selection.

(
gc();t2=timestamp();hf = heapfree
with redraw off (
    
    delete objects
    obj = plane widthSegments:90 lengthSegments:90 width:100 length:100 isselected:on
    convertToPoly obj
    obj.useSoftSel = on
    fsel = #{}
    for f=1 to polyop.getNumFaces obj where (abs (polyop.getFaceCenter obj f).y) < 5 do fsel[f] = true
    polyop.setFaceSelection obj fsel
    subObjectLevel = 4
    redrawViews()
    
    
    getData = polyop.getVDataValue
    setData = polyop.setVDataValue

    ssZero = #{}
    ssNonZero = #()
    
    t1=timestamp()
    for i = 1 to polyop.getNumVerts obj do 
    (
        f = getData obj 1 i
        
        case of 
        (
            (f > 0.999) : ssZero[i] = true
            (f < 0.001) : ssZero[i] = true
            default   : ssNonZero[i] = f            
        )

    )
    format "Get values       % sec
" ((timestamp() - t1)/1000 as float)
    
    obj.useSoftSel = off
    
    t1=timestamp()
    setData obj 1 ssZero 0.0
    format "Set zeroes       % sec
" ((timestamp() - t1)/1000 as float)
    
    t1=timestamp()
    for i = 1 to polyop.getNumVerts obj where ssNonZero[i] != undefined do setData obj 1 i ssNonZero[i]
    format "Set nonzeroes    % sec
" ((timestamp() - t1)/1000 as float)
    
    t1=timestamp()
    update obj
    format "Updating         % sec
" ((timestamp() - t1)/1000 as float)
    
    polyop.setFaceSelection obj #{}
)
redrawViews()
format "Time: %sec. Mem: %
" ((timestamp()-t2)/1000 as float) (hf-heapfree)
)

and the updated version which works fast enough
The trick was to group indexes by value and then set value for the whole group. Sure it introduces some error to initial values but it is acceptable.
