ADPD188BI and Application Wavetool examples

Hello devs,

I was wondering which is the difference or in which is recommended use case for each example: ADPD188BIZ-SK_EVAL_SMOKE_chop_01.dcfg and ADPD188BIZ-SK_TEST_SMOKE_OpenAir_01.dcf

for the Chop example, I notice it has a lower sample frequency and more consumption in LEDs, 4 pulses sequence and it uses an integrator for the photodiode signal (chop)

for the OpenAir example higher sample frequency and lower consumption in LEDs, 8 pulses sequence

Which are the benefits of using one or another regarding smoke detection? because of both returns differents PTR values for the same smoke exposition
