How to Mark specific text in a pattern BOLD through defined Variable using wildcard

My current code loops through range A62:A5000 (fixed / static range), and searches for word "PETER", wherever it find, it marks the text "PETER" Bold.

Dim xFind As String
Dim xCell, xTxtRg, xRg As Range
Dim xCount As Long
Dim xLen, xStart As Integer

On Error Resume Next
Set xRg = Activesheet.Range("A62:A5000") 
'On Error Resume Next
Set xTxtRg = Application.Intersect(xRg.SpecialCells(xlCellTypeConstants, xlTextValues), xRg)

If xTxtRg Is Nothing Then
Exit Sub
End If
'where specific text found
xFind = "PETER" 
xLen = Len(xFind)
    
For Each xCell In xTxtRg
xStart = InStr(xCell.Value, xFind)
Do While xStart > 0
    xCell.Characters(xStart, xLen).Font.Bold = True
    xCount = xCount + 1
    xStart = InStr(xStart + xLen, xCell.Value, xFind)
Loop
Next

What I am now looking is to change the variable content, currently

xFind = "PETER"

to something like XFind = PETER SPACE and if this pattern with prefix PETER is found, to format only this portion of PETER + Pattern as bold within entire

Illustrations
PETER 4.3x ' no action PETER and anything >=5 with suffix .0x be marked as bold
PETER 5.2x ' since it is PETER blank space >=5, then entire PETER 5.2x portion be marked bold
PETER 305.2x ' since it is PETER blank space >=5, then entire PETER 305.2x portion be marked bold
PETER 2.2x ' since it is PETER blank space <5, then entire PETER 2.2x portion not be formatted

Content of any cell within Range A62:A5000 would have multiple lines (smaple workbook attached), but idea is to find where PETER + >= 5.0x is found and same (selected text in defined pattern) be formatted as bold

Without running the above code given in sample workbook, I have manually highlighted to illustrate what objective I want to achieve.
