Newbie questions about PCC

Hi

I've been reading the https://wiki.mikrotik.com/wiki/Manual:PCC, and also I've seen lots of users PCC configs. There's one thing I don't understand in the manual, specifically the lines of the mangle rules:

add chain=prerouting in-interface=ISP1 connection-mark=no-mark action=mark-connection \
    new-connection-mark=ISP1_conn
add chain=prerouting in-interface=ISP2 connection-mark=no-mark action=mark-connection \ 
    new-connection-mark=ISP2_conn

Why prerouting and not input? The text says that these connections are "connection initiated from outside"...

Another question here in these lines:

add dst-address=0.0.0.0/0 gateway=10.111.0.1 distance=1 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=10.112.0.1 distance=2 check-gateway=ping

Why distances are different? On several PCC configurationes I've seen, distance are the same.
Regards

Connections from outside can go to the router (input) or can pass through to a device behind (forward), using prerouting you intercept both.

Why distances are different? On several PCC configurationes I've seen, distance are the same.

Those two lines say: in the MAIN routing table install a default gateway (10.111.0.1) and check it with ping, if 10.111.0.1 is unreachable than the route become invalid and next distance route is the new default gateway. The second route must have higher distance in order to be inactive when first is active, otherwise you would have ECMP (https://en.m.wikipedia.org/wiki/Equal-c ... th_routing).
