Instead of having a blocks target gas fixed to be exactly 1/2 of the gas limit of a block. What would happen if every 8192 epochs we take the average gas price for the last 8192 epochs and if it’s below (with some margin) a certain constant g we decrease the gas target by 1/1024 if it’s above, we increase it. This will prevent gas prices being too high/low for extended periods but keep them able to react short term. Maybe also adding a hard max limit of 3/4 of the gas limit.
Edit: After doing some math, it appears that this has the opposite effect, making it 10x more unstable.
