ok, will definitely forget any per block retargetting, it would cause too many problems (convergence/...), and TRC really needs to get more stable now.
testnet now retargets every 9 blocks, using timings from the last 108 blocks. Every retarget is limited to +/- 1/12th.
Livechain will retarget at 180 blocks intervals (6hours) using timings from the last 2160 blocks (3days). Every single retarget is limited to 1/12th.
pushing code and will later build/publish a dev windows build.
now "ramping up" testnet and doing a few tests.
and finally:

will test this for 1 or 2 days on testnet before merging code up (release then master branches), will then release code with choosen block height for the switch over.
dev-0.1.3-143 published with active testnet code.
