I hope tomorrow morning after VPS update, MOST OF samples I sent will get detected. ATM, only 5 more detected by streaming updates (as there were not any AV updates since this morning) but I’m sure after next VPS update many more samples will be detected.
You need to be patient,sometimes the reaction times for certain not in the wild samples can be slow…atleast what I have noticed…so keep sending and dont loose hope 
btw,just submitted 500 pieces of malicious binaries to avast labs! ;D
If their automated analysis systems do not detect the samples after analysis, they have to check sample manually and that takes a bit more time.
In-the-wild malware tend to get higher attention and priority.
They usually do not answer automatically to the submissions.
Rescan the files within Chest and check if any of them got detected by avast!
