I oversaw one .cch file. The 1:31 is from the SRPL_1960_10.cch file.
ClassRecord="Brabham BT20 1966",16,91.1650,-1.0000,-1.0000
That's why both times are stored in the blt file, once from SRPL_1960_10.cch and once from BRABHAMBT20_1966_CHALLANGE_10.cch. The upload doesn't check for "dublicate" entries tough and it simply takes the last time/entry instead of the best one.
