Restaurant review sites use a star system for the overall experience, Amazon has a similar system for books, and we have the overall rating out of 10. How relevant and useful is this rating though?<!--more--><\/p>\n<p>Maintaining the accuracy and fairness of the ratings in the system is part of our mission, and we&#8217;re committed to upholding that. The recent <a href=\"http:\/\/www.tabletennisdb.com\/blog\/rating-quality-updates\/\" target=\"_blank\">rating quality update<\/a> received a lot of criticism surrounding the erasing of &#8220;overall&#8221; ratings below 5\/10, and it was justified criticism.<\/p>\n<p>As I ponder the best way to maintain fair ratings, I keep wondering about the usefulness of this overall rating. Here are my thoughts so far, and I&#8217;d like your feedback on this.<\/p>\n<h2>1. &#8220;Overall&#8221; is different for everyone.<\/h2>\n<p>I see a lot of reviews where a rubber didn&#8217;t live up to the player&#8217;s expectations of it. Maybe the throw angle was too low, the sponge too hard, or loops just didn&#8217;t seem to work well. But for every dissatisfied reviewer that gave it a 4\/10, there were several more players who loved it. So if we all have different playing styles that fit different types of equipment, what truly deserves a bad overall rating?<\/p>\n<h2>2. Universally bad characteristics.<\/h2>\n<p>Personally, I&#8217;d only rate a product low if it had characteristics that are bad for <em>any<\/em> player (for example:\u00a0quality issues).<\/p>\n<p><strong>Always bad<\/strong><\/p>\n<ul>\n<li>Does the rubber wear out quickly?<\/li>\n<li>Does the topsheet peel off the sponge from regular play?<\/li>\n<li>Did the shoes fall apart after a month?<\/li>\n<li>Do balls jam in the robot frequently?<\/li>\n<\/ul>\n<p><strong>Not always bad<\/strong><\/p>\n<ul>\n<li>The rubber is too tacky for me (some people were meant for non-tacky rubbers)<\/li>\n<li>The blade is too hard (it doesn&#8217;t fit your style)<\/li>\n<li>My loops aren&#8217;t landing on the table (this one&#8217;s really vague, and may mean that the setup isn&#8217;t a good fit for your strokes, or a change in technique is required to use it effectively)<\/li>\n<\/ul>\n<p>Certain characteristics are universally bad, and I believe only those should negatively impact a product&#8217;s rating.<\/p>\n<h2>3. Don&#8217;t rely too heavily on the overall rating.<\/h2>\n<p>After reading lots of reviews and ratings, I&#8217;ve concluded that, currently, the overall rating describes these factors:<\/p>\n<ol>\n<li>How well it fits the style of the &#8220;majority&#8221; of its users (popularity)<\/li>\n<li>Quality control issues<\/li>\n<\/ol>\n<p>Note that &#8220;how good a racket is&#8221; isn&#8217;t part of this list. Because you can&#8217;t simplify a rubber to one score. You can rate its popularity or specific physical properties, but there&#8217;s no way to generalize that to &#8220;good&#8221; or &#8220;bad&#8221;.<\/p>\n<p>In most cases, it&#8217;s #1 that is more heavily impacting this rating, not quality issues, and this makes it problematic for anyone relying heavily on the overall rating to get insight on the product.<\/p>\n<h1>Conclusion<\/h1>\n<p>So is the overall rating useless? Not quite, but its usefulness is limited.<\/p>\n<p>If you&#8217;re looking for the next blade to buy, don&#8217;t just look at what gets a 9.5\/10. Look for the specific characteristics you need (level of tackiness, speed, sponge hardness) and that will give you the best chance of finding your perfect setup. There&#8217;s no silver bullet that works for everyone.<\/p>\n<p>Remember, equipment doesn&#8217;t magically make you play well. You need to find what fits <em>you<\/em>. It will take some trial and error, but get some advice from your peers (and especially a knowledgeable coach if you have one).<\/p>\n<p><em><strong>Should &#8220;Overall&#8221; rating be removed?<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve always struggled with the &#8220;overall&#8221; rating that is put on a product.
