After years of watching gymnastics, the one thing I believe with judges is that they judge the routine they see. At some meets, it will feel like judges are taking every possible deduction, at others gymnasts will receive scores you know they won't see again same season. But unless you have the same judges on the same event at every meet - you cannot and should not try to figure out why Susie got a 8.75 on floor last week and a 9.2 this week. Because each judge is judging the routine they see.
This isn't a product of 'level', or taking the minimum versus maximum deduction. I think this is a function of each level having its own requirements and deductions and each judge having their own 'special' bugaboos when working within the judging system. After 5 years of competing in one region - there are some judges whose scoring I am pretty familiar with at this point. I 'know' what deductions those judges hit hard, and what deductions they don't because I have watched countless routines at level 3, 4, 5, 6, 7 and 8 (as well as fewer but many) routines at Level 9 and 10.
Some judges really hit hard on bent legs or lack of pointed toes. Some seem to stress turns or leaps. It just depends on what specific thing catches that judge's eye particularly within a routine or event. From watching/listening to judges work over the years working at meets - it is as equally common for 2 judges to reach the exact same score watching the same routine...but having 'caught' different deductions for the routine as it is for judges to be 0.4 points or more off from one another and again hearing them talk about the different deductions they each saw.
