It seems that you get a different score whether you input a same variant formatted as insertion versus a duplication

hg19
    NC_000011.9:g.47364695_47364697dup
    NC_000011.9:g.47364694_47364695insACC
    same variant , different score

Considering that the resulting sequence is identical shouldn't the score be the same?

TAC|ct becomes TACCAC|ct for both 11-47364697-C-CACC or 11-47364694 - T-TACC
