Hi Pablo, Thanks so much for your explanation!
Also, for prom client in the do fn, do we need to initialize them in the setup code? My concern is that if we have this initialization in each do fn, we might overwhelm the memory. I think we can pass them as the parameter? Do you have a recommissioned way to do that not to hurt the performance? Will try that out to see if this is workable!
