Frequent testing and dosing are incompatible with infrequent visits from a pool service, period. They are apples and oranges in terms of methods of pool care. Yes, the basic principles of using accurate knowledge can apply to both, but a pool service will quickly realize that for non-SWCG pools they either need to use Trichlor pucks and minimize the chlorine usage and use some supplement to prevent algae or they have to use high CYA levels and dose high enough to have chlorine last through the week.
In fact, these are the two basic methods used by all pool services, though they don't all realize why they do what they have stumbled upon doing. In the Trichlor puck camp, some pool services use copper-based algaecides, some use phosphate removers, some use weekly algaecides (linear quats or Polyquat), fewer use bromide. They vary in the FC levels they target and hardly any raise the FC as the CYA level climbs (that's where proper education would help). Some have CYA maximums where they will do partial drain/refill to lower the CYA. The pool service associated with the store where I get my chlorinating liquid services 2000 pools using Trichlor tabs either in floating dispensers or inline chlorinators, has a target 4.5 ppm FC, and if algae develops in a pool they first shock it and if the algae later returns then they use a phosphate remover. They also do partial drain/refill when the CYA exceeds 100 ppm. Note that by using supplemental algaecides or phosphate removers, that one can lower chlorine demand by half or more since one can target lower FC/CYA levels and have lower chlorine losses from sunlight and other sources. This slows down CYA buildup. If one can get to around 1 ppm FC per day usage, then the CYA buildup is 18 ppm per month while CYA loss still slowly occurs. So one can usually go for a 5-month season this way without having to dilute the water to reduce CYA.
In the dose once a week camp (i.e. don't use Trichlor), there are pool services that dose with chlorinating liquid (or Cal-Hypo in areas with low CH if it's less expensive) and/or chlorine gas (or a combination of the two) where they have a 100 ppm or higher CYA level and dose to 14 ppm FC resulting in around 4 ppm FC at the end of the week in time for the next visit.
In theory, a pool service could install a peristaltic pump or The Liquidator, but when I asked my local pool store about that they said that their clients generally don't want chemicals on-site due to safety for their kids. For whatever reason, having chlorinating liquid in a pool shed (even if in a locked container) is seen to be more hazardous than Trichlor pucks in a floating dispenser or inline chlorinator.
