Parameters in Identification tab of FAME retention index GC/MS data

Hi, I would like to know why it is recommend to use 2000-3000 in the FAME retention index.

Parameters: If you put retention time (RT) information in your MSP file, set the RT tolerance value (default is 0.5). In the case that you choose ‘retention index’ as the identification index, set about 10-20 for alkane (Kovats index) and about 2000-3000 for FAME (Fiehn index) for ‘Retention index tolerance’.

Thank you in advance.
