My point scores are for me. When I evaluate a wine blind, whether a single bottle or others of its peer group, I find it essential to be able to quantify the impression it makes on my palate. I could not care less if others believe that I am way too stingy as I've read some people say, while others taunt me and say my scores are too high. For them, maybe that is true. My scores might appear different than theirs. I am pleased if that is the case. That is because I am scoring based on my own likes, dislikes, stylistic preferences, and experience.
So, honestly my scores probably are not all that useful to others, except as a guideline and for comparison sake. If someone has been reading my TNs for any length of time, they will quickly learn if my palate is in synch with theirs or not. For example, I rarely agree with Alex B. when it comes to scores we both come up with or often times Port that he likes better or ones where I prefer them. Basically, often times that is just do to having a preference for different qualities and styles in VP. That said, I have the deepest respect for Alex's innate sense of Port and appreciate his keen palate. So, when using any critic, amateur or professional to base your own buying decision ... first you must learn to calibrate your palate vs. the critic's and see if they are typically two points higher (as an example) or lower. That said, there is no better buying guide than trying wines for yourself (whether Port/Madeira or otherwise) and making your own qualitative assessments.
I have only once or twice in my life looked at a Wine Advocate for more than two minutes. I have not received the WS in thre or four years and Decanter I let lapse two years ago too. I love reading tasting notes, but find more to enjoy from the notes here on

from deeply impassioned amateur Madeira & Port lovers than I do from Parker, Suckling, Mayson, Liddell, Broadbent, Jancis, etc. It is the enthusiasm in their discoveries that I so enjoy. Tasting notes without a score are still worthy, but I find the score helps me to quickly calibrate where the taster/writer (famous or not)is coming from.
A great tasting note not only provides a pantry listing of what one smells and the flavors one tastes, but it must convey a visceral and sensorial impression for me to get real enjoyment from it. There was a post by Otto from Finland on a Verdelho he had tasted recently, that I just posted on. It was a fantastic TN and I felt like I was sitting next to him tasting the same wine.
That is what I love about a well written tasting note. Nevertheless, without a score ... I feel unsettled and the TN seems a bit ... well, incomplete.
Last but not least. I take pride in this. The guys who've been drinking/evaluating wine with me on a monthly basis for years now ... say that sometimes I look for too much good in wines that they find issues with. One in particular thinks just the opposite, saying I am always the one to point out the TCA or oxidation in a wine, however ... I'd have to say he's right about noting flaws. As a group though, the greatest compliment they've paid me over the years is saying that no matter what they think of my scores ... they see my ratings as very consistent ... blind or not.
Sorry I can't compete with you guys ... ich bin ein Berliner, is about the extent of my non-vinous Deutch.
