The Scotland stand-off scored a try, three penalties and four conversions for a personal haul of 22 points during the 51-24 win over Munster, and now he's determined to build on that platform to bolster the Scotstoun side's PRO12 play-off charge.
Ruaridh told the Evening Times: "I guess the Munster game was probably my best for Glasgow.
"I have been with Warriors for five years now and I don't remember having too many games as special as that. But now I have produced that level of display I must try and maintain it over the last three games of the season, starting with Scarlets on Friday week.
"But I think a big part of that has been the help I have had from Gregor Townsend and the style of rugby he has us playing. We have some serious pace in the backline and everyone is comfortable with the off-loading rugby Gregor is preaching.
"With the pack we have, we are getting the type of ball to put it all together and really hurt sides, and you saw that in the second half against Munster.
"To be putting 51 points on a team like them, with all that experience of having won European Cups, is unheard of. I am really enjoying my rugby, but at the same time I'm much more aware of what I need to be doing and when I need to be doing it.
"The ultimate test of that performance against Munster will be my ability to reproduce it over the last three league games and hopefully into the play-offs."
After slotting all seven kicks against Munster, Ruaridh admitted his kicking confidence is at an all-time high as Glasgow prepare for the crucial last three games of the regular season, saying: "I am just trying to visualise and focus on them and it worked well against Munster.
"A home semi-final in the play-offs is the target. We have taken bonus-point wins over Ulster, Cardiff and Munster in our last three games at Scotstoun. With our huge support backing us, we would fancy ourselves against anyone in a home semi."
