distance paths are different than in readme.md

[aguaviva]

I index the images using:

(base) $ ~/repos/clip.cpp/build$ bin/image-search-build -m ./models/CLIP-ViT-B-32-laion2B-s34B-b79K_ggml-model-f16.gguf  ../tests/
clip_model_load: description:  two-tower CLIP model
clip_model_load: GGUF version: 2
clip_model_load: alignment:    32
clip_model_load: n_tensors:    397
clip_model_load: n_kv:         24
clip_model_load: ftype:        f16

clip_model_load: text_encoder:   1
clip_model_load: vision_encoder: 1
clip_model_load: model size:     289.06 MB
clip_model_load: metadata size:  0.13 MB

clip_model_load: 24 MB of memory allocated
main: starting base dir scan of '../tests/'

main: processing 2 files in ''
.main: 2 images processed and indexed

And here are the distances as computed in the readme.md the problem is that I am getting different values

(base) $ ~/repos/clip.cpp/build$ bin/image-search apple

clip_model_load: GGUF version: 2

search results:
distance path
  0.711100 ../tests//red_apple.jpg
  0.779483 ../tests//white.jpg

How could I tell what is right?
