Let me thow in a couple thoughts.
First thought, on weight:
Actually, light weight is the biggest factor for any given length.

This is a real problem for those who use their boats for non-racing cruises because we have everything on board: food, bedding, full tanks of water and fuel, spares, books, anchoring gear, refrigeration instead of an ice box, large house bank and start battery, outboard (for the dingy), ..... and the list goes on. When I put the boat away for the season it takes several trips with a F-150 long bed to bring everything home.
The rating is based upon being in full race mode (or words to that effect). So ..., Wanna race competitively for that weekend? Learn to strip the boat of everything you can.
Second thought, on the Rater, or measurer:
If the area you're in has an established rating for your boat you may be good to go. Normally that means existing boats of the same make and model as the one you have. However, bring in a new boat and the rating you get will be up to the rater. Speaking from experience, as the skipper of "Kiwi Express" (one of the better/best performing boats) said to me prior to my one and only PHRF race, "He didn't do you no favor." As it turned out, he didn't.
As has been said in the posts above, the higher the number the better, and seconds count. After paying fees to join PHRF Northwest, getting a rater for our area (west Puget Sound) assigned, the boat ('88 Hunter 35) was given a rating of 118. Had no clue at the time where that fit in the fleet but it didn't take long to find out. One of the boats in our class was a Hobie 33.
Third thought:
Want to revisit your rating? That's not so easy. From what I found out, one has to essentially file something like a protest then go before a (rating?) board to defend why it should be different. Not exactly something a novice really wants to do.
I've heard it said that it takes time for the racers to move up the ladder and it isn't all about learning how to sail or tricking the boat out (although that part helps). Re-evaluating one's boat rating appears to be one of the methods.
The annual dues I paid was for the calendar year (not a year from the time I joined) and that was the last race of the year. Ouch! Live and learn. Decided not to re-join the next year, or ever since. That is really too bad because, in spite of everything, it really was fun. On the 6-hour race, came in 4th, 2' 30" behind first (the Hobie 33) and just seconds behind 3rd place (the Boat of the Year boat). Chances of getting a better number after that was slim to none, even though a lot of it was totally dumb luck and tactics!!! Unfortunately, the good results would never have helped "in court" (before the board). Shot myself in the foot? I think so.
It's too bad there can't be some kind of adjustment for a cruising (non-racing) configuration but I can understand why because that would be very difficult to apply and enforce. It's bad enough even when everybody is in racing configuration and there are still those who bend or break the rules. Big boats especially are getting too expensive to own in order to have a dedicated racing boat. With more stringent environmental rules targeting recreational boats and boatyards being turned into condominiums big boat ownership will become more expensive so trailerable boats will probably be the future.
