Nice scores Hentie!
You must try 30min some day, i think you can reach 300000 with plastic (that's my long time aim).
I did plastic 30min set yesterday and managed to make new records on 10, 20 and 30 minutes.
First 5min i toke quite easy (48500), but 10min marker i already made new record (95900). After 15min spinning started to feel easy again as allways and i managed to made new record on 20 minutes also (192000). Last 10min went quickly and before i know 30min was past with new record 287000.
I have now done one month work with metal to improve my plastic scores and it worked. 30min score jumped from 281500 to 287000.
My plastic needs also some repair, i think i have to put new shells and innards.
I just realized that i havent done any speedrun sessions in two months, this endurancing is so addictive.
