protocol adjustment
...
if we are loosing a burst ACK because of fading signals or bad conditions or just because - combined with a changing speed level - theres now a good chance we are not loosing the entire data frame because of a corrupted CRC, anymore. We are now searching in already received data, if our new (smaller) data chunk already exists. If so, we are stripping the entire data to this position and adding our new data chunk. If not, it seems we received new data the regulary way. However, this could cause problems if we have a too small data entropie. We might also check if we have an increased NACK counter or if a data chunk exists, twice or more - in a further step
