| Parametric Case | Weightage: % of similarity | Notes |
| In the case where letters are phonetically identical | 100 | |
| In the case letters are Similar but differs by a consistant singular pattern of iotation. But has examples of common cognates that shows the derivation of iotation. | 75 | Since it’s a positive similarity, weightage is raised above 50% |
| In the case letters are Similar but differ by a consistant singular pattern of iotation. But has no examples of common cognates that shows the derivation of iotation. | 20 | |
| There are no direct similarities within corresponding vowel or consonant set, but similar sound can be shown with compound letters or syllabic context | 40 | The weightage is given closer to the positive threshold |
| Not similar | 0 |
