You're preaching my gospel Rob.......even got the same name ! There're too many people kidding themselves that taking longer to do a task produces a better result, when in reality many are taking longer, either because they're not efficient, or worse still, they take longer and try to justify their overcharging by taking a lot longer, but only covering the same ground, so to speak.
Sure there are some very large suites that will take twice as long as an " average " 3 pce and some are very " fussy " with extra cushions, deep buttons, swirls, etc, but we're talking average here.
If you are slow, you can speed up by being more efficient in your approach and use of products. Some like to give the impression that everything they do is " by the book " and is the " only way "whereas most change their practices as the gain experience, experiment and realise that their customers expectation, for instance, is not to have their furniture dry as you leave, so why take an extra half hour towelling and blasting with fans when it's totally unnecessary.
Also, the extent of pre vaccing that's occasionally mentioned is nuts and again adding unnecessarily to the total time taken. Again.............there will be occasional suites that need more prepping than others, but getting back to averages.....................I average 90 mins per suite with the occasional one taking longer and I use dry foam a lot, but occasionally use other products, eg, microsplitters or colloidals.
There's no ALWAYS and no NEVER.
