How much do entity pages grow if you add snak IDs to the output?

script.sh

for id in Q$RANDOM Q$RANDOM Q$RANDOM Q$RANDOM Q$RANDOM; do
    html=$(curl -s "https://www.wikidata.org/wiki/$id");
    bytesCurrent=$(printf '%s' "$html" |
        wc -c);
    bytesWithId=$(printf '%s' "$html" |
        sed 's|class="wikibase-snakview"|class="wikibase-snakview wikibase-snakview-0000111122223333444455556666777788889999"|g' |
        wc -c);
    LC_ALL=C printf '%s\nCurrent: %8d bytes\nWith ID: %8d bytes\nChange: %.3f%%\n---\n' \
        "$id" \
        "$bytesCurrent" \
        "$bytesWithId" \
        "$(bc <<< "scale=10; 100 * ($bytesWithId/$bytesCurrent - 1)")";
done

A very large example entity to test is Q21558717.
