200μs of NEO/go without sha1 case is still questionable:

T(transmit request) = 10μs (deco rx throttle) + t(link-tx-request)
T(transmit answer)  = 10μs·4.5 (~ 4.5 KB answer for 4K ZData) + teco.rx-delay (= 3μs ?)

	vv

T(link) ~= 60μs

T(teco-local,no-sha1,NEO/go) was ~= 100μs (see time-sep17-teco.txt)
T(deco-local,no-sha1,NEO/go) was ~=  20μs (see time-sep17-deco.txt)

T(teco-deco,no-sha1,NEO/go) = 100μs/2 + 20μs/2 = 60μs ?

if so RTT(getobject) should be 60+60 = 120μs  but we have 200μs.
