Well, no - ALL paceline dependent factors in RDSS are dependent on how a given horse compares (ranks) against the other horses in the analysis set.

Since BL is a weighed composite of rankings of the 7 Primary factors it comprises, let's take just 1 Factor: TPR (or CPR) rank: which is itself a sum of EPR+ LPR, then that sum ranked. If one horse has a TPR rank (check the TPR Tab) - say a 3, and another horse is ranked 2 (i.e. its TPR is higher than the the 3rd ranked horse), then - that rank 2 gets more weight in the BLBL calculation than the rank 3. Continue that process for all 7 Factors.

So, you can see, even without tinkering with which paceline you choose for a horse, horses' weighted BLBL numbers will be relative to each other. If a horse scratches, the BL may well change (the scratched horse with rank 1s and 2s will cause lower ranked horses to inherit those higher ranks and adjust their BLBL score). If you demote a horse to the Secondary group or Non-Contender group (or remove them entirely from the Analysis set - NOT RECOMMENDED) - same effect on the weighted ranking process. Etc.

BLBL is dependent on 1) which line you choose for the horse (or let the software choose) and 2) which other horses' ranks a given horse is being compared to.
