Statistical methods used by Airbnb are totally inaccurate and give a ralse impression of both host and quests. Apparently Airbnb has not invested in people who know anything about qualitatitive and quantitative analysis or statistical methods and market(review) survey construction.
Best possible score any host can get is a total of 30 stars on each review.
(6 categories times 5 stars equals 30 stars ) thata 100 percent right
If a guests gives 4 stars in one category and 5 in all others the score is 29 stars out of 30 possible....or 29 d ivided by 30 which equals 96.66666 percent. That score is what should be shown in the overall rating It should also be used for overall rating by adding it to the totals f rom each review..then dividing that by the number of reviews.
Thus if I get 5 reviews. 4 are 100 percent and 1 is 80 percent ...480 total points divided by 5 equals 93.25...percent....
This would make the rating scale much more accurate and FAIR
Ranges for scoring should be clearly defined and superhost status should be based upon A level performance ...90 to 100 percent of the time
all 6 categories are 90 percent or above
5 stars in 6 Categories equals 100 percent perfection ( no need to change or improve )!
4 stars in 6 categories equals 80 percent( room to tweek things up a notch in 6 categories) but just for this outlier who is not going to sink my whole average
3 stars in 6 categories equals 60 percent...( a major outlier ) but one in 20 or 30 having a bad day is not going to blow my superhost starltus off the map and I wilp make an extra effort to white glove dust over the doorways before the next inspector general checks in!.)
Etc.
Best possible senerio for hosts and guests would be for Airbnb to set up algorithims to translate stars into. Percentages and fairly weighting the stars guest give.
Publishing the rating scale along with the request to review and a desc rpition of what sc our es are required to be super host and maintain that status would really help.
Eventually Airbnb should also base a weighted review score on the numbers of the of days a guest stays...long stays require consistently high performance to get 100...shoter stays require quicker advance prep..etc.
Bottom line...taoe it or leave it Airbnb is going to set things up the way that works for them...and Im going to provide super hosting experience s for my guests whether they think Im a 4 or a 5 ...I think they are fortunate to be allowed to come into my home and stay...
