Hello,

Almost all my TXs have relatively large size compared to their similar ones.

Take this as an example, that should be the slimmest TX in size as it has only 1 input and only 1 output.

This one is 339 Bytes similar TXs should be like 192 or so.

A second one with 1 input and 2 outputs has a size of 372, similar ones are 226 bytes

What is actually the reason behind this? I am running electrum
