Just further to my previous post, despite having a profitable week laying the Place, it would have been doubly profitable if I hadn't relied on the bot! Of the 10 accidents 8 could be attributable to the bot not being able to filter selections.
2 accidents were Return from a Spell horses
2 accidents were 2nd return from a spell horses
1 accident was a first starter
3 accidents were that the bot Layed bets based on order of favouritism on Lay side, not Back side.
Let's say I want to Lay the 6th Fav, well in these thin markets the 6th Favourite on the Lay side might be the 4th favourite on the Back side! Lesson learnt for novices like me.

To conclude, you can sacrifice profit just using a bot, but it's a tradeoff between that and having time to yourself, to do other things. (Researching more 'Grail' ideas...lol)
