How many "write to action log" does it take to affect performance

As the triggers are executed consistently there is no limit except your hard disk's performance.

I am not having much joy writing to log files in a way that I can analyse to results in Excel.

Does anyone have a good experience of how to separate expressions in the write command so that they appear in a single cell (for example) when opened in Excel?

For example:

sel_name   back_price  "5 mins before off"

General comments about opening log files easily in Excel also appreciated - there seems to be a few ways of getting log data to Excel and all have different results in the way the data is displayed.

thanks

OK thanks vey much for your reply - yes I get that bit, but to use those values in Excel it would be helpful to have the values and the selection names in separate adjacement cells so you can performs vlookup() functions etc.   I am struggling to get anything useful into excel that would not take a macro or complex formula to separate out.  All the data appears in column A of the spreadsheet and no delimiter (tab, comma, space etc) seems to get it in a good order.
