T-value Calculation

I searched PCdmis help menu & this forum and couldn't find the formula that the software is using for calculation the reported T-values. Does anybody have this information?

I have some historic XYZ data & current data. The current data has T-values reported but the historic data does not. The customer wants to know the difference in historic & current data based only on the T-values.

Thanks in advance for your assistance.

You could also :
ASSIGN/V1=DOT(SCN1.HIT[1..SCN1.NUMHITS].XYZ-SCN1.HIT[1..SCN1.NUMHITS].TXYZ,SCN1.HIT[1..SCN1.NUMHITS].TIJK)
Then :
ASSIGN/V2=MININDEX(V1)
ASSIGN/V3="SCN1.HIT[V2]"
PNTMIN =GENERIC/POINT,DEPENDENT,CARTESIAN,$
NOM/XYZ,<V3.TX,V3.TY,V3.TZ>,$
MEAS/XYZ,<V3.X,V3.Y,V3.Z>,$
NOM/IJK,<V3.TI,V3.TJ,V3.TK>,$
MEAS/IJK,<V3.I,V3.J,V3.K>
ASSIGN/V4=MAXINDEX(V1)
ASSIGN/V5="SCN1.HIT[V4]"
PNTMAX =GENERIC/POINT,DEPENDENT,CARTESIAN,$
NOM/XYZ,<V5.TX,V5.TY,V5.TZ>,$
MEAS/XYZ,<V5.X,V5.Y,V5.Z>,$
NOM/IJK,<V5.TI,V5.TJ,V5.TK>,$
MEAS/IJK,<V5.I,V5.J,V5.K>

I did initially go this route (for sure there are many ways to skin the cat) but MIN/MAXINDEX was too slow on my setup.

It's surprising that a loop goes quickly than an array...
