Re: are there any actual stats on chain reorgs, by depth?

very nice! didnt know it listed all reorgs.
so if I read that right since block 395487, the max depth reorg has been: 1

if so, does that mean a node that has been constantly running for 1 year would be needed to run getchaintips, to get the entire year's history of reorgs?

It seems 10 blocks at current hashrate would be very rare

More or less. But remember that the reorganizations aren't really globally identical. You'll really want several long-running nodes on several ISPs to have meaningful statistics.

Also, testnet has way more and longer reorgs, very good for testing the handling of the reorgs.

reorgs are totally dependent on each node, yes. but if your node is seeing max reorg depth of 1, i would think any node that is actually connected to the internet and not being flooded, would not be seeing reorgs of 10 blocks

For testing I can just manually force a reorg, I just wanted to calibrate things with the right initial offset using current network characteristics

3 seems too low, but 10 should be at most a monthly occurance, which is fine for a several minute recalc. But if anybody has more extensive data or much worse reorgs, please post!

it could be 2112's node is special
