Bind of make_digits calo_raw_bank=False in HltEfficiencyChecker examples

In the HLT1+HLT2 chained examples, the following bind is called (e.g. at hlt1_and_hlt2_eff_example.py#L35):

make_digits.global_bind(calo_raw_bank=False)

When investigating the efficiencies of dilepton triggers recently with equivalent options, the inclusion of this bind caused a drop in efficiency of factor O(100). Without the bind, the options run absolutely fine, returning sensible efficiencies.

Is this line really required/can it be removed?

(p.s. this issue is somewhat of a placeholder, planning to run tests with/without bind this week)
