Fibroscan results keep trending in opposite directions!

Hi all! I’m a 31 year old male. Was diagnosed with fatty liver about 2 years ago had a Cap score of 394 and 5.5 kpa at that time so F0. Continued to spiral and eat horribly for about a year then got on Zepbound and lost about 30 pound about 6 months prior to a follow up in Nov of this past year and cap score went down to 294 but my kpa went up to 7.8 and was diagnosed with F2. Got off meds and started exercising and eating cleaner and in mid March of this year got another fibroscan with 254 cap score and 9.3 kpa. So now solidly in F2-F3. My ALT and AST in the 20-40 range (normal). Fib 4 score .36. Overall, feel like I’m getting better but seems fibrosis is worsening. Wanted to check in and see how accurate a fibroscan might be? I’m having a follow up this Friday to check in and talk to my GI. I have read about fibrosis lagging behind but it’s been on an upward trajectory with cap score going down so feel a bit worried.
