Taking procedures from (relatively) powerful twin turbine aircraft and applying them to R44s is not a practical or realistic way to operate.
For those earning a living using the aircraft as a tool - probably not, but they are likely to be more experienced and better trained and therefore far more likely to anticipate problems and be better placed to deal with them if they occur..
Those with PPLs and low time would be better served to give themselves as much safety margin as possible.
Operating into confined areas at close to max gross weight is something to be done very carefully and progressively.
